4. YARN

5. WHY?

6. https://www.domo.com/

7. Building new applications

9. Can I use my existing tools?

10. (Big) Data Platform
(Big) Data Project

11. Ingest
Store
Process
Consume

12. Ingest Data

13. Copy files in HDFS
hadoop fs -put dailylogs-log.zip /logs/2015/09/10/

14. Import RDBMS data
sqoop import --connect jdbc:mysql://db.foo.com/somedb --table
customers --target-dir /incremental_dataset --append
Files
HBase
Hive

15. Import RDBMS data
input {
jdbc {
jdbc_connection_string => "jdbc:postgresql://localhost:5432/mydb"
jdbc_user => "postgres"
jdbc_driver_library => "/path/to/postgresql-9.4-1201.jdbc41.jar"
jdbc_driver_class => "org.postgresql.Driver"
statement => "SELECT * from contacts"
}
}

16. What’s “wrong”?
Batch????

17. Streaming
Flume, Kafka, Logstash
to the rescue

18. Log
App Events
Twitter
Sensors
…
HDFS
MapR-FS
Alerts
Elasticsearch
…
DB

19. Log

Producers Consumers

20. Stream data into Hadoop using Flume
Server

HBase
Hive

21. Streams using Kafka

22. Stream data using Logstash

23. Data Storage
Data Format

24. How to store your data?
• Files in a distributed file system
• Rows in NoSQL Table
• Index in Search Engine

25. Process Data

26. Data Processing
• Transform the data
• Enrich the data
• Examples:
• Store data in multiple formats
• Aggregate data
• Build Recommendations
• ….

27. MapReduce Processing Model
• Define mappers
• Shuffling is automatic
• Define reducers
• For complex work, chain jobs together
– Use a higher level language or DSL that does this for you

28. Apache Spark: Fast Big Data
– Rich APIs in Java,
Scala, Python
– Interactive shell
• Fast to Run
– General execution
graphs
– In-memory storage

29. Spark: Unified Platform
Spark SQL
Spark Streaming
(Streaming)
MLlib
(Machine learning)
Spark (General execution engine)
GraphX (Graph
computation)
Mesos
Distributed File System (HDFS, MapR-FS, S3, …)
Hadoop YARN

30. Elasticsearch / Watcher

32. Query the data

33. Files
HBase
Hive
Index
Discovery/Analytics

34. SQL strikes back!

35. Files
HBase
Hive
SQL on Hadoop
• SQL Shell
• JDBC ODBC
• BI Tools
• Reporting

36. Elasticsearch

37. Kibana as a frontend

38. Example: Recommendation Platform

39. Machine Learning
MapR Cluster
HBase
MapR DB
MapR-FS
Add recommendations
to movies
Capture Ratings
Movies & Recommendations
Movie Database

40. Conclusion
• If possible use Streams: Kafka, Logstash
• Advanced Data Processing and Machine Learning : Spark
• Expose your data using SQL for your “BI folks” : Drill
• Aggregation and Full Text Search : Elasticsearch
• Data Visualisation : Kibana
