3. The MapR Distribution for Apache Hadoop
 The open, enterprise-grade distribution for Apache Hadoop
– Open source components
• Hive, Pig, Cascading, HBase, ZooKeeper, Oozie, Flume, Sqoop, Whirr, …
– Enhancements to make Hadoop more open and enterprise-grade
 Fastest growing distribution
– Thousands of clusters deployed
 Now available as a service with Amazon Elastic MapReduce (EMR)
– http://aws.amazon.com/elasticmapreduce/mapr

4. Recent News
 Amazon selects MapR to provide the enterprise-grade Hadoop
distribution in EMR
 Google selects MapR to provide Hadoop on Google Compute
Engine
 MapR launched open source Apache Drill project inspired by
Google Dremel
– Low latency queries

6. Not All Applications Use the Hadoop APIs
Applications and libraries
that use files and/or SQL
30 years
100,000s applications
10,000s libraries
10s programming languages
Applications and libraries
that use the Hadoop APIs

7. Hadoop Needs Industry-Standard Interfaces
Hadoop • MapReduce and HBase applications
API • Mostly custom-built
• File-based applications
NFS • Supported by most operating systems
• SQL-based tools
ODBC • Supported by most BI applications and
query builders

8. NFS

9. Your Data is Your Data
 HDFS-based Hadoop distributions do not (cannot)
support NFS
 Your data is your data – make sure you can access it
– Why store your data in a system which cannot be accessed
by 95% of the world’s applications and libraries?

10. The NFS Protocol
 RFC 1813 WRITE3res NFSPROC3_WRITE(WRITE3args) = 7;
struct WRITE3args {
nfs_fh3 file;
 Very simple protocol offset3 offset;
count3 count;
stable_how stable;
 Random reads/writes opaque data<>;
– Read count bytes from };
offset offset of file file
– Write buffer data to READ3res NFSPROC3_READ(READ3args) = 6;
offset offset of a file file
struct READ3args {
nfs_fh3 file;
offset3 offset;
 HDFS does not support count3 count;
random writes so it };
cannot support NFS

16. Customer Examples: Import/Export Data
 Network security vendor
– Network packet captures from switches are streamed into the cluster
– New pattern definitions are loaded into online IPS via NFS
 Online measurement company
– Clickstreams from application servers are streamed into the cluster
 SaaS company
– Exporting a database to Hadoop over NFS
 Ad exchange
– Bids and transactions are streamed into the cluster

17. Customer Examples: Productivity and Operations
 Retailer
– Operational scripts are easier with NFS than DFS + MapReduce
• chmod/chown, file system searches/greps, make, tab-complete
– Consolidate object store with analytics
 Credit card company
– User and project home directories on Linux gateways
• Local files, scripts, source code, …
• Administrators manage quotas, snapshots/backups, …
 Large Internet company
– Web server serve MapReduce results (item relationships) directly from cluster
 Email marketing company
– Object store with HBase and NFS

21. ODBC
 ODBC – Open DataBase Connectivity
– Open standard API for accessing a SQL-based backend
– Developed by Microsoft and Simba Technologies in 1992
 Flagship API for SQL-based BI and reporting
– Excel, Tableau, MicroStrategy, Crystal Reports, …
 Advanced ODBC drivers use the latest 3.52 specification
©MapR Technologies - Confidential 21

22. MapR ODBC Driver
 MapR provides a Hive ODBC 3.52 driver
– Developed in partnership with ODBC inventor Simba Technologies
– Compliant with latest ODBC 3.52 specification
• 32- and 64-bit platform support
• Windows and Linux
 Enables direct SQL access to MapR-stored data by translating SQL to
HiveQL
 SQLizer enables seamless connectivity
– Provides ANSI SQL-92 front-end
– Targeted for existing apps that generate standard SQL queries
– Transforms SQL query into HiveQL query
