          Components: mapred
    Affects Versions: 0.19.1, 0.19.0
         Environment: Java 1.6, HAdoop0.19.0, Linux..Oracle,

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
