Brandon Williams commented on CASSANDRA-3045:
---------------------------------------------

bq. How do you configure BOF vs CFOF?

By calling setOutputFormatClass on the job.

bq. Why do we need to keep CFOF around?

I can think of two reasons: firstly, by removing it, we break every existing job.  This is pretty easy for users to fix though, as indicated above.  Secondly, someone might want access to each individual record as soon as possible, rather than waiting for the entire job to finish and stream a bunch of sstables.  It's a latency vs throughput tradeoff.
