Issue Type: Bug
Components: task
Affects Versions: 1.0.3, 0.20.203.0
Reporter: Luke Lu
Assignee: Luke Lu

Tom White commented on MAPREDUCE-4400:
--------------------------------------
The same issue was fixed in trunk and branch-2 in MAPREDUCE-3809 in much the same way. How about backporting that code to branch-1?

@Shinivas: have you tried this with mapreduce.tasktracker.outofband.heartbeat=true? (needs a cluster restart of course).

[jira] [Updated] (MAPREDUCE-4400) Fix performance regression for
small jobs/workflows
Posted by "Luke Lu (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/MAPREDUCE-4400?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Luke Lu updated MAPREDUCE-4400:
-------------------------------
Attachment: mapreduce-4400-branch-1.patch
MAPREDUCE-2450 fixed the communication race condition that can cause occasional 1 minute timeout but make the PROGRESS_INTERVAL sleep pretty much mandatory. Any tasks including setup and cleanup tasks would need to sleep at least 3 seconds to finish.
The patch make the wait interruptable when tasks finish.
With this patch and MAPREDUCE-4399 and outofband heartbeats, PigMix is about 20% faster than 0.20.2. These patches makes Hadoop 1.x series on par with Hadoop 2.x in terms of general performance.

--------------------------------
Tags: task, performance
Resolution: Fixed
Fix Version/s: 1.1.1
Hadoop Flags: Reviewed
Thanks for the review and +1, Shrinivas and Tom! Created MAPREDUCE-4477 to track trunk improvement. Committed the change to branch-1 and branch-1.1. It's not in 1.1.0-rc1 though.

Shrinivas Joshi commented on MAPREDUCE-4400:
--------------------------------------------
Hi Luke - In our experiments your patch did achieve the same effect as what MAPREDUCE-4381 was trying to in terms of performance. We noticed good performance gains on Mahout KMeans clustering workload (~ 4%). It would be nice if we can get the branch-1 version of your change reviewed and checked-in in the mean time. Thanks.

Luke Lu commented on MAPREDUCE-4400:
------------------------------------
Yes. The speed up is more pronounced with outofband heartbeat, which has similar effect of MAPREDUCE-1906 (which is not in branch-1). MRv2 doesn't need this patch as it was addressed by MAPREDUCE-3809. Tom, can we file a separate jira to improve the change in trunk?
Shrinivas, you're encouraged to review and +1 on the patch :)

As I said earlier, I did verify that this patch was working as expected. It does minimize synchronization over MR3809. This patch looks good to be committed to me.
