org.apache.hadoop.mapred.lib.db.DBInputformat not working with oracle
---------------------------------------------------------------------
Key: HADOOP-5482
URL: https://issues.apache.org/jira/browse/HADOOP-5482
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Affects Versions: 0.19.1, 0.19.0
Environment: Java 1.6, HAdoop0.19.0, Linux..Oracle,
Reporter: evanand
Priority: Blocker
org.apache.hadoop.mapred.lib.db.DBInputformat not working with oracle.
The out of the box implementation of the Hadoop is working properly with
mysql/hsqldb, but NOT with oracle.
Reason is DBInputformat is implemented with mysql/hsqldb specific query
constructs like "LIMIT", "OFFSET".
FIX:
building a database provider specific logic based on the database providername
(which we can get using connection).
I HAVE ALREADY IMPLEMENTED IT FOR ORACLE...READY TO CHECK_IN CODE
