You mean BulkOutputFormat isn't working, or MO isn't working at all?
BulkOutputFormat isn't working because it's still checking to make sure the
output CF has been set and throwing an exception otherwise. I'm happy to
remove this check but we don't use BOF so I don't have the bandwidth to test.
I'll create the patch if you want to do so.

> 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.
