> 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
