Hadoop to the Rescue!
• Easy to use! (Pig, Hive, Cascading)
• CHEAP: 1% the cost of SAN/NAS
• A department can afford its own Hadoop cluster!

• Dump all your data in one place: Hadoop DFS
• Silos come CRASHING DOWN!
• JOIN like crazy!
• ETL like whoah!

• An army of mappers and reducers at your command
• OMGWTFBBQ ITS SO GREAT! I FEEL AWESOME!

NOW WHAT?

?

Analytics Apps: It takes a Team
• Broad skill-set
• Nobody has them all
• Inherently collaborative


Data Science Team
• 3-4 team members with broad, diverse skill-sets that overlap

• Transactional overhead dominates at 5+ people

• Expert researchers: lend 25-50% of their time to teams

• Creative workers. Run like a studio, not an assembly line

• Total freedom... with goals and deliverables.

• Work environment matters most


How to get insight into product?
• Back-end has gotten t-h-i-c-k-e-r

• Generating $$$ insight can take 10-100x app dev

• Timeline disjoint: analytics vs agile app-dev/design

• How do you ship insights efficiently?

• How do you collaborate on research vs developer timeline?

The Wrong Way - Part One

“We made a great design. Your job is to predict the future for it.”


The Wrong Way - Part Two

“Whats taking you so long to reliably predict the future?”


The Wrong Way - Part Three

“The users don’t understand what 86% true means.”


The Wrong Way - Part Four

GHJIAEHGIEhjagigehganbanbigaebjnain!!!!!RJ(@J?!!


The Wrong Way - Inevitable Conclusion

Reminds me of... the waterfall model

:( 26

Chief Problem

You can’t design insight in analytics applications.

You discover it.

You discover by exploring.


-> Strategy

So make an app for exploring your data.

Iterate and publish intermediate results.

Which becomes a palette for what you ship.


Data Design

• Not the 1st query that = insight, its the 15th, or the 150th
• Capturing “Ah ha!” moments
• Slow to do those in batch...

• Faster, better context in an interactive web application.
• Pre-designed charts wind up terrible. So bad.
• Easy to invest man-years in the wrong statistical models
• Semantics of presenting predictions are complex, delicate

• Opportunity lies at intersection of data & design


How do we get back to Agile?


Statement of Principles

(then tricks, with code)


Setup an environment where...

• Insights repeatedly produced
• Iterative work shared with entire team
• Interactive from day 0

• Data model is consistent end-to-end
• Minimal impedance between layers
• Scope and depth of insights grow
• Insights form the palette for what you ship

• Until the application pays for itself and more


Value document > relation

Most data is dirty. Most data is semi-structured or un-structured. Rejoice!

Value document > relation

Note: Hive/ArrayQL/NewSQL’s support of documents/array types blur this distinction.

Relational Data = Legacy Format
• Why JOIN? Storage is fundamentally cheap!

• Duplicate that JOIN data in one big record type!

• ETL once to document format on import, NOT every job

• Not zero JOINs, but far fewer JOINs

• Semi-structured documents preserve data’s actual structure

• Column compressed document formats beat JOINs! (paper
coming)

Value imperative > declarative
• We don’t know what we want to SELECT.
• Data is dirty - check each step, clean iteratively.
• 85% of data scientist’s time spent munging. See: ETL.

• Imperative is optimized for our process.
• Process = iterative, snowballing insight
• Efficiency matters, self optimize


Value dataflow > SELECT


Ex. dataflow: ETL + email sent count

© Hortonworks Inc. 2012 (I can’t read this either. Get a big version here.) 38

Value Pig > Hive (for app-dev)
• Pigs eat ANYTHING
• Pig is optimized for refining data, as opposed to consuming it
• Pig is imperative, iterative
• Pig is dataflows, and SQLish (but not SQL)
• Code modularization/re-use: Pig Macros
• ILLUSTRATE speeds dev time (even UDFs)
• Easy UDFs in Java, JRuby, Jython, Javascript
• Pig Streaming = use any tool, period.
• Easily prepare our data as it will appear in our app.
• If you prefer Hive, use Hive.
But actually, I wish Pig and Hive were one tool. Pig, then Hive, then Pig, then Hive...
See: HCatalog for Pig/Hive integration, and this post.


Localhost vs Petabyte scale: same tools
• Simplicity essential to scalability: highest level tools we can
• Prepare a good sample - tricky with joins, easy with
documents
• Local mode: pig -l /tmp -x local -v -w
• Frequent use of ILLUSTRATE
• 1st: Iterate, debug & publish locally
• 2nd: Run on cluster, publish to team/customer
• Consider skipping Object-Relational-Mapping (ORM)
• We do not trust ‘databases,’ only HDFS @ n=3.
• Everything we serve in our app is re-creatable via Hadoop.


Data-Value Pyramid

Climb it. Do not skip steps. See here.


0/1) Display atomic records on the web


0.0) Document-serialize events
• Protobuf
• Thrift
• JSON

• Avro - I use Avro because the schema is onboard.


0.1) Documents via Relation ETL
enron_messages = load '/enron/enron_messages.tsv' as (
message_id:chararray,
sql_date:chararray,
from_address:chararray,
from_name:chararray,
subject:chararray,
body:chararray
);

enron_recipients = load '/enron/enron_recipients.tsv' as ( message_id:chararray, reciptype:chararray, address:chararray, name:chararray);

split enron_recipients into tos IF reciptype=='to', ccs IF reciptype=='cc', bccs IF reciptype=='bcc';

headers = cogroup tos by message_id, ccs by message_id, bccs by message_id parallel 10;
with_headers = join headers by group, enron_messages by message_id parallel 10;
emails = foreach with_headers generate enron_messages::message_id as message_id,
CustomFormatToISO(enron_messages::sql_date, 'yyyy-MM-dd HH:mm:ss') as date,
TOTUPLE(enron_messages::from_address, enron_messages::from_name) as from:tuple(address:chararray, name:chararray),
enron_messages::subject as subject,
enron_messages::body as body,
headers::tos.(address, name) as tos,
headers::ccs.(address, name) as ccs,
headers::bccs.(address, name) as bccs;

store emails into '/enron/emails.avro' using AvroStorage(

Example here.

0.2) Serialize events from streams
class GmailSlurper(object):
...
  def init_imap(self, username, password):
    self.username = username
    self.password = password
    try:
      imap.shutdown()
    except:
      pass
    self.imap = imaplib.IMAP4_SSL('imap.gmail.com', 993)
    self.imap.login(username, password)
    self.imap.is_readonly = True
...
  def write(self, record):
    self.avro_writer.append(record)
...
  def slurp(self):
    if(self.imap and self.imap_folder):
      for email_id in self.id_list:
        (status, email_hash, charset) = self.fetch_email(email_id)
        if(status == 'OK' and charset and 'thread_id' in email_hash and 'froms' in email_hash):
          print email_id, charset, email_hash['thread_id']
          self.write(email_hash)

© Hortonworks Inc. 2012 Scrape your own gmail in Python and Ruby. 45

0.3) ETL Logs

log_data = LOAD 'access_log'
USING org.apache.pig.piggybank.storage.apachelog.CommongLogLoader
AS (remoteAddr,
remoteLogname,
user,
time,
method,
uri,
proto,
bytes);


1) Plumb atomic events -> browser

(Example stack that enables high productivity)


Lots of Stack Options with Examples
• Pig with Voldemort, Ruby, Sinatra: example
• Pig with ElasticSearch: example
• Pig with MongoDB, Node.js: example

• Pig with Cassandra, Python Streaming, Flask: example
• Pig with HBase, JRuby, Sinatra: example
• Pig with Hive via HCatalog: example (trivial on HDP)
• Up next: Accumulo, Redis, MySQL, etc.


1.1) cat our Avro serialized events

me$ cat_avro ~/Data/enron.avro
{
u'bccs': [],
u'body': u'scamming people, blah blah',
u'ccs': [],
u'date': u'2000-08-28T01:50:00.000Z',
u'from': {u'address': u'bob.dobbs@enron.com', u'name': None},
u'message_id': u'<1731.10095812390082.JavaMail.evans@thyme>',
u'subject': u'Re: Enron trade for frop futures',
u'tos': [
{u'address': u'connie@enron.com', u'name': None}
]
}

© Hortonworks Inc. 2012 Get cat_avro in python, ruby 49

1.2) Load our events in Pig

me$ pig -l /tmp -x local -v -w
grunt> enron_emails = LOAD '/enron/emails.avro' USING AvroStorage();
grunt> describe enron_emails

emails: {
message_id: chararray,
datetime: chararray,
from:tuple(address:chararray,name:chararray)
subject: chararray,
body: chararray,
tos: {to: (address: chararray,name: chararray)},
ccs: {cc: (address: chararray,name: chararray)},
bccs: {bcc: (address: chararray,name: chararray)}
}


1.3) ILLUSTRATE our events in Pig
grunt> illustrate enron_emails

---------------------------------------------------------------------------
| emails |
| message_id:chararray |
| datetime:chararray |
| from:tuple(address:chararray,name:chararray) |
| subject:chararray |
| body:chararray |
| tos:bag{to:tuple(address:chararray,name:chararray)} |
| ccs:bag{cc:tuple(address:chararray,name:chararray)} |
| bccs:bag{bcc:tuple(address:chararray,name:chararray)} |
---------------------------------------------------------------------------
| |
| <1731.10095812390082.JavaMail.evans@thyme> |
| 2001-01-09T06:38:00.000Z |
| (bob.dobbs@enron.com, J.R. Bob Dobbs) |
| Re: Enron trade for frop futures |
| scamming people, blah blah |
| {(connie@enron.com,)} |
| {} |
| {} |
Upgrade to Pig 0.10+

1.4) Publish our events to a ‘database’
From Avro to MongoDB in one command:
pig -l /tmp -x local -v -w -param avros=enron.avro
-param mongourl='mongodb://localhost/enron.emails' avro_to_mongo.pig

Which does this:
/* MongoDB libraries and configuration */
register /me/mongo-hadoop/mongo-2.7.3.jar
register /me/mongo-hadoop/core/target/mongo-hadoop-core-1.1.0-SNAPSHOT.jar
register /me/mongo-hadoop/pig/target/mongo-hadoop-pig-1.1.0-SNAPSHOT.jar

/* Set speculative execution off to avoid chance of duplicate records in Mongo */
set mapred.map.tasks.speculative.execution false
set mapred.reduce.tasks.speculative.execution false
define MongoStorage com.mongodb.hadoop.pig.MongoStorage(); /* Shortcut */

/* By default, lets have 5 reducers */
set default_parallel 5

avros = load '$avros' using AvroStorage();
store avros into '$mongourl' using MongoStorage();

© Hortonworks Inc. 2012 Full instructions here. 52

1.5) Check events in our ‘database’
$ mongo enron

MongoDB shell version: 2.0.2
connecting to: enron

> show collections
emails
system.indexes

> db.emails.findOne({message_id: "<1731.10095812390082.JavaMail.evans@thyme>"})
{
" "_id" : ObjectId("502b4ae703643a6a49c8d180"),
" "message_id" : "<1731.10095812390082.JavaMail.evans@thyme>",
" "date" : "2001-01-09T06:38:00.000Z",
" "from" : { "address" : "bob.dobbs@enron.com", "name" : "J.R. Bob Dobbs" },
" "subject" : Re: Enron trade for frop futures,
" "body" : "Scamming more people...",
" "tos" : [ { "address" : "connie@enron", "name" : null } ],
" "ccs" : [ ],
" "bccs" : [ ]
}


1.6) Publish events on the web

require 'rubygems'
require 'sinatra'
require 'mongo'
require 'json'

connection = Mongo::Connection.new
database = connection['agile_data']
collection = database['emails']

get '/email/:message_id' do |message_id|
data = collection.find_one({:message_id => message_id})
JSON.generate(data)
end


1.6) Publish events on the web


Whats the point?
• A designer can work against real data.
• An application developer can work against real data.
• A product manager can think in terms of real data.

• Entire team is grounded in reality!
• You’ll see how ugly your data really is.
• You’ll see how much work you have yet to do.
• Ship early and often!

• Feels agile, don’t it? Keep it up!


1.7) Wrap events with Bootstrap
<link href="/static/bootstrap/docs/assets/css/bootstrap.css" rel="stylesheet">
</head>
<body>
<div class="container" style="margin-top: 100px;">
<table class="table table-striped table-bordered table-condensed">
<thead>
{% for key in data['keys'] %}
<th>{{ key }}</th>
{% endfor %}
</thead>
<tbody>
<tr>
{% for value in data['values'] %}
<td>{{ value }}</td>
{% endfor %}
</tr>
</tbody>
</table>
</div>
</body> Complete example here with code here.

1.7) Wrap events with Bootstrap


Refine. Add links between documents.

Not the Mona Lisa, but coming along... See: here

1.8) List links to sorted events
Use Pig, serve/cache a bag/array of email documents:
pig -l /tmp -x local -v -w

emails_per_user = foreach (group emails by from.address) {
sorted = order emails by date;
last_1000 = limit sorted 1000;
generate group as from_address, emails as emails;
};

store emails_per_user into '$mongourl' using MongoStorage();

Use your ‘database’, if it can sort.
mongo enron
> db.emails.ensureIndex({message_id: 1})
> db.emails.find().sort({date:0}).limit(10).pretty()
{
{
" "_id" : ObjectId("4f7a5da2414e4dd0645d1176"),
" "message_id" : "<CA+bvURyn-rLcH_JXeuzhyq8T9RNq+YJ_Hkvhnrpk8zfYshL-wA@mail.gmail.com>",
" "from" : [
...


1.8) List links to sorted documents


1.9) Make it searchable...
If you have list, search is easy with ElasticSearch and Wonderdog...

/* Load ElasticSearch integration */
register '/me/wonderdog/target/wonderdog-1.0-SNAPSHOT.jar';
register '/me/elasticsearch-0.18.6/lib/*';
define ElasticSearch com.infochimps.elasticsearch.pig.ElasticSearchStorage();

emails = load '/me/tmp/emails' using AvroStorage();
store emails into 'es://email/email?json=false&size=1000' using ElasticSearch('/me/
elasticsearch-0.18.6/config/elasticsearch.yml', '/me/elasticsearch-0.18.6/plugins');

Test it with curl:
curl -XGET 'http://localhost:9200/email/email/_search?q=hadoop&pretty=true&size=1'

ElasticSearch has no security features. Take note. Isolate.


From now on we speed up...

Don’t worry, its in the book and on the blog.

2) Create Simple Charts


2) Create Simple Tables and Charts


2) Create Simple Charts
• Start with an HTML table on general principle.
• Then use nvd3.js - reusable charts for d3.js
• Aggregate by properties & displaying is first step in entity
resolution
• Start extracting entities. Ex: people, places, topics, time series
• Group documents by entities, rank and count.

• Publish top N, time series, etc.
• Fill a page with charts.
• Add a chart to your event page.

2.1) Top N (of anything) in Pig


top_things = foreach (group things by key) {
sorted = order things by arbitrary_rank desc;
top_10_things = limit sorted 10;
generate group as key, top_10_things as top_10_things;
};
store top_n into '$mongourl' using MongoStorage();

Remember, this is the same structure the browser gets as json.

This would make a good Pig Macro.


2.2) Time Series (of anything) in Pig

/* Group by our key and date rounded to the month, get a total */
things_by_month = foreach (group things by (key, ISOToMonth(datetime))
generate flatten(group) as (key, month),
COUNT_STAR(things) as total;

/* Sort our totals per key by month to get a time series */
things_timeseries = foreach (group things_by_month by key) {
timeseries = order things by month;
generate group as key, timeseries as timeseries;
};

store things_timeseries into '$mongourl' using MongoStorage();

Yet another good Pig Macro.


Data processing in our stack

A new feature in our application might begin at any layer... great!

omghi2u!
I’m creative! I’m creative too! where r my legs?
I know Pig! I <3 Javascript!
send halp

Any team member can add new features, no problemo!

Data processing in our stack

... but we shift the data-processing towards batch, as we are able.

See real example here.
Ex: Overall total emails calculated in each layer

3) Exploring with Reports


3.0) From charts to reports...

• Extract entities from properties we aggregated by in charts (Step 2)

• Each entity gets its own type of web page

• Each unique entity gets its own web page
• Link to entities as they appear in atomic event documents (Step 1)

• Link most related entities together, same and between types.

• More visualizations!

• Parametize results via forms.


3.1) Looks like this...


3.2) Cultivate common keyspaces


3.3) Get people clicking. Learn.
• Explore this web of generated pages, charts and links!
• Everyone on the team gets to know your data.
• Keep trying out different charts, metrics, entities, links.

• See whats interesting.
• Figure out what data needs cleaning and clean it.
• Start thinking about predictions & recommendations.

‘People’ could be just your team, if data is sensitive.


4) Predictions and Recommendations


4.0) Preparation
• We’ve already extracted entities, their properties and relationships

• Our charts show where our signal is rich

• We’ve cleaned our data to make it presentable
• The entire team has an intuitive understanding of the data

• They got that understanding by exploring the data

• We are all on the same page!


4.2) Think in different perspectives
• Networks

• Time Series / Distributions

• Natural Language Processing

• Conditional Probabilities / Bayesian Inference

• Check out Chapter 2 of the book...
© Hortonworks Inc. 2012 See here. 79

4.3) Networks


4.3.1) Weighted Email Networks in Pig

DEFINE header_pairs(email, col1, col2) RETURNS pairs {
filtered = FILTER $email BY ($col1 IS NOT NULL) AND ($col2 IS NOT NULL);
flat = FOREACH filtered GENERATE FLATTEN($col1) AS $col1, FLATTEN($col2) AS $col2;
$pairs = FOREACH flat GENERATE LOWER($col1) AS ego1, LOWER($col2) AS ego2;
}

/* Get email address pairs for each type of connection, and union them together */
emails = LOAD '/me/Data/enron.avro' USING AvroStorage();
from_to = header_pairs(emails, from, to);
from_cc = header_pairs(emails, from, cc);
from_bcc = header_pairs(emails, from, bcc);
pairs = UNION from_to, from_cc, from_bcc;

/* Get a count of emails over these edges. */
pair_groups = GROUP pairs BY (ego1, ego2);
sent_counts = FOREACH pair_groups GENERATE FLATTEN(group) AS (ego1, ego2), COUNT_STAR(pairs) AS total;


4.3.2) Networks Viz with Gephi


4.3.3) Gephi = Easy


4.3.4) Social Network Analysis


4.4) Time Series & Distributions


/* Count things per day */
things_per_day = foreach (group things by (key, ISOToDay(datetime))
generate flatten(group) as (key, day),
COUNT_STAR(things) as total;

/* Sort our totals per key by day to get a sorted time series */
things_timeseries = foreach (group things_by_day by key) {
timeseries = order things by day;
generate group as key, timeseries as timeseries;
};

store things_timeseries into '$mongourl' using MongoStorage();


4.4.2) Regress to find Trends
JRuby Linear Regression UDF Pig to use the UDF

Trend Line in your Application


4.5.1) Natural Language Processing

import 'tfidf.macro';
my_tf_idf_scores = tf_idf(id_body, 'message_id', 'body');

/* Get the top 10 Tf*Idf scores per message */
per_message_cassandra = foreach (group tfidf_all by message_id) {
sorted = order tfidf_all by value desc;
top_10_topics = limit sorted 10;
generate group, top_10_topics.(score, value);
}

© Hortonworks Inc. 2012 Example with code here and macro here. 88

4.5.2) NLP: Extract Topics!


4.5.3) NLP for All: Extract Topics!

• TF-IDF in Pig - 2 lines of code with Pig Macros:
• http://hortonworks.com/blog/pig-macro-for-tf-idf-makes-
topic-summarization-2-lines-of-pig/

• LDA with Pig and the Lucene Tokenizer:
• http://thedatachef.blogspot.be/2012/03/topic-discovery-
with-apache-pig-and.html


4.6) Probability & Bayesian Inference


4.6.1) Gmail Suggested Recipients


4.6.1) Reproducing it with Pig...


4.6.2) Step 1: COUNT(From -> To)


4.6.2) Step 2: COUNT(From, To, Cc)/Total

P(cc | to) = Probability of cc’ing someone, given that you’ve to’d someone


4.6.3) Wait - Stop Here! It works!

They match...


4.4) Add predictions to reports


5) Enable new actions


Why doesn’t Kate reply to my emails?
• What time is best to catch her?

• Are they too long?

• Are they meant to be replied to (contain original content)?

• Are they nice? (sentiment analysis)

• Do I reply to her emails (reciprocity)?

• Do I cc the wrong people (my mom) ?
