Aaron Kimball commented on MAPREDUCE-716:
-----------------------------------------
Thanks for the review Enis.
The Hudson failures are, of course, unrelated to this patch. There's no new
tests because this patch consists of two things; vendor-specific logic which
requires drivers incompatible with Apache (mysql, Oracle), and a refactoring.
Since we can't check in MySQL's or Oracle's JDBC drivers, Hudson can't test
those codepaths. I've used Sqoop + MAPREDUCE-716 to import from Oracle and
MySQL, so I've confirmed locally that it works. The refactoring doesn't really
require a new test, the existing test plan should cover it.

> 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
