Mck SembWever updated CASSANDRA-2388:
-------------------------------------

    Attachment: CASSANDRA-2388.patch

Initial attempt at solution. Although I'm a little apprehensive to the additions to cassandra.thrift

I've tested that existing hadoop jobs work but the new functionality hasn't been tested (as i currently don't have any RF=2 data setup).
