Introducing Hadoop
•A new approach to data processing and data storage
•Rather than a small number of large, powerful servers, it spreads processing over
large numbers of small, cheap, redundant servers
•Spreads the data you’re processing over
lots of distributed nodes
•Has scheduling/workload process that sends
parts of a job to each of the nodes
- a bit like Oracle Parallel Execution
•And does the processing where the data sits
- a bit like Exadata storage servers
•Shared-nothing architecture
•Low-cost and highly horizontal scalable

Apache Hive : SQL Access + Table Metadata Over HDFS
•Apache Hive provides a SQL layer over Hadoop, once we understand the structure (schema)
of the data we’re working with
•Exposes HDFS and other Hadoop data as tables and columns
•Provides a simple SQL dialect for queries called HiveQL
•SQL queries are turned into MapReduce jobs under-the-covers
•JDBC and ODBC drivers provide
access to BI and ETL tools
•Hive metastore (data dictionary)
leveraged by many other Hadoop tools
‣Apache Pig
‣Cloudera Impala
‣etc
SELECT a, sum(b)
FROM myTable
WHERE a<100
GROUP BY a

and Apache Hive Physical Layer database type
‣But practically, it comes with limitations
‣Current 11.1.1.7 version of OBIEE only ships with HiveServer1 ODBC drivers
‣HiveQL is a limited subset of ISO/Oracle SQL
‣… and Hive access is really slow

Summary
•Oracle Big Data SQL extends Exadata capabilities over Hadoop and Hive
•Makes Hive Metastore visible through Oracle Data Dictionary
•Register Hive tables as ORACLE_HIVE external tables and include in Oracle SQL queries
•Used with OBIEE, allows RPDs to be created across both Oracle + Hive data, with
query federation handled by Oracle RBDMS rather than BI Server
•Enables use of Oracle Advanced Analytics functions over Hadoop data
•Useful for ODI as way of using full set of join operators on Hive data, and simplifying
the addition of Hive data to Oracle mappings
•For developers working with Exadata + BDA, useful addition to the data access toolkit
