Robbie Strickland updated CASSANDRA-4208:
-----------------------------------------

    Attachment: cassandra-1.1-4208-v4.txt

I've attached a new patch that removes the check for a null output CF on BulkOutputFormat.  This allows BOF to use the MultipleOutputs API.

> It is not currently possible to output records to more than one column family in a single reducer.  Considering that writing values to Cassandra often involves multiple column families (i.e. updating your index when you insert a new value), this seems overly restrictive.  I am submitting a patch that moves the specification of column family from the job configuration to the write() call in ColumnFamilyRecordWriter.
