Doğacan Güney commented on HBASE-940:
-------------------------------------
Does this mean that after HBASE-847, if MapOutputValueClass is BatchUpdate,
reduce will have to clone BatchUpdate objects before output.collect? Because if
that is the case, I think a lot of MR jobs will break.
> Make the TableOutputFormat batching-aware

> With HBASE-748, we can batch updates but the auto-flushing is enabled by
> default. Make it that it is disabled for MR jobs outputting in a table and
> make sure that everything is sent in the end.
