              Is this also a sub-task of MAPREDUCE-3561?

              Yeah, I couldn't find this ticket before.

              But my guess is most of those sub-tasks are related and most likely will be fixed in one shot. Let's see.

              This was mostly due to misconfiguration, but MAPREDUCE-3641 does help a lot.

              Compression is now 10.4% faster in .23 (compared to .205/1.0). Please close this jira

              Thanks for the update Amol. Thanks to Sid and Vinay who've been running this and verifying it.

              This is fixed now after the recent commits tracked at MAPREDUCE-3561.
