> For better compatibility with hadoop, I would like to add old style hadoop support (mapred) to the ColumnFamilyInputFormat and ColumnFamilyRecordReader.  We already have it in the output.  Oozie in particular handles the old style api better.  That is the motivation for us.  I already did this as part of my patch for CASSANDRA-1497 so it should be trivial.  We are just in a tight schedule right now and I'll come back to this once we have a bit of breathing room.
> I think it would help with compatibility with other systems that rely on hadoop as well.
