New in OBIEE 11.1.1.7 : Hadoop Connectivity through Hive
•OBIEE 11.1.1.7 can now access Hadoop environments, through “Hive”
•Hive is a query environment over Hadoop/MapReduce to support SQL-like queries
•Hive server accepts HiveQL queries via HiveODBC or HiveJDBC, automatically
creates MapReduce jobs against data previously loaded into the Hive HDFS tables
•Approach used by ODI and OBIEE to gain access to Hadoop data
•Allows Hadoop data to be accessed just like any other data source

Hadoop, and the Big Data Ecosystem
•Apache Hadoop is one of the most well-known Big Data technologies
‣Family of open-source products used to store, and analyze distributed datasets
‣Hadoop is the enabling framework, automatically parallelises and co-ordinates jobs
‣MapReduce is the programming framework
for filtering, sorting and aggregating data
‣Map : filter data and pass on to reducers
‣Reduce : sort, group and return results
‣MapReduce jobs can be written in any
language (Java etc), but it is complicated
•Can be used as an extension of the DW staging layer - cheap processing & storage
•And there may be data stored in Hadoop that our BI users might benefit from

Hive as the Hadoop “Data Warehouse”
•MapReduce jobs are typically written in Java, but Hive can make this simpler
•Hive is a query environment over Hadoop/MapReduce to support SQL-like queries
•Hive server accepts HiveQL queries via HiveODBC or HiveJDBC, automatically
creates MapReduce jobs against data previously loaded into the Hive HDFS tables
•Approach used by ODI and OBIEE
to gain access to Hadoop data
•Allows Hadoop data to be accessed just like
any other data source (sort of...)

How Hive Provides SQL Access over Hadoop
•Hive uses a RBDMS metastore to hold
table and column definitions in schemas
•Hive tables then map onto HDFS-stored files
‣Managed tables
‣External tables
•Oracle-like query optimizer, compiler,
executor
•JDBC and OBDC drivers,
plus CLI etc

External Tables

Dealing with Hadoop / Hive Latency Option 1 : Exalytics
•Hadoop access through Hive can be slow - due to inherent latency in Hive
•Hive queries use MapReduce in the background to query Hadoop
•Spins-up Java VM on each query
•Generates MapReduce job
•Runs and collates the answer
•Great for large, distributed queries ...
•... but not so good for “speed-of-thought” dashboards
•So what if we could use Exalytics to speed-up Hadoop queries?

Oracle Exalytics In-Memory Machine

•Combination of high-end hardware (Sun x86_64 architecture, 3RU rack-mountable, 1-2TB RAM)
and optimized versions of Oracle’s BI, In-Memory Database and OLAP software
•Delivers “in-memory analytics” focusing on analysis, aggregation and UI
‣Rich, interactive dashboards with split-second response times
‣1-2TB (and now 4TB) of RAM, to run your analysis in-memory
‣Infiniband connection to Exadata and Oracle BDA
‣40 CPU cores (and now 128) to support high user numbers
‣Lower TCO through known configuration,
combined patch sets
‣Contains software features only licensable through
Exalytics package

Exalytics as the Query Performance Enhancer
•In conjunction with a well-tuned data warehouse, Exalytics adds an in-memory analysis layer
•Based around Oracle TimesTen for Exalytics, Oracle’s In-Memory Database
•Aggregates are recommended based on query patterns, automatically created in TimesTen
•Summary Advisor makes recommendations, which adapt as queries change
•Meant to be “plug-and-play” - no need for
expensive data warehouse tuning
•So can we use this for speeding-up Hadoop/Hive queries?

Dealing with Hadoop / Hive Latency Option 2 : Use Impala

•Cloudera Impala is an open-source but
commercially-sponsored in-memory MPP platform
•Replaces Hive and MapReduce in the Hadoop stack
•Can we use this, instead of Hive, to access Hadoop?
‣It will need to work with OBIEE

•Accesses standard HDFS file data
•Option to use Apache AVRO, RCFile,

Impala / OBIEE Issue with ORDER BY Clause
•Although checking rows in the BI Administration tool worked, any query that aggregates
data in the dashboard will fail
•Issue is that Impala requires LIMIT with all ORDER BY clauses
‣OBIEE could use LIMIT, but doesn’t for Impala
at the moment (because not supported)
•Workaround - disable ORDER BY in
Database Features, have the BI Server do sorting
‣Not ideal - but it works, until Impala supported
