Jonathan Gray commented on HBASE-974:
-------------------------------------
TableReduce has had some performance issues in the past. I think it's pretty

Yes, you'll definitely want to turn off autoflush. Honestly I don't think that
option existed when these jobs were written :)
I will close these issues once I open an 0.20 issue.
