Jonathan Gray commented on HBASE-974:
-------------------------------------

TableReduce has had some performance issues in the past.  I think it's pretty 
good now though.

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.
