> Key: MAPREDUCE-2170
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2170
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Components: jobtracker
> Affects Versions: 0.22.0
> Environment: GNU/Linux
> Reporter: Harsh J
> Assignee: Harsh J
> Priority: Critical
> Fix For: 0.23.0
>
> Attachments: mapreduce.loadaverage.r3.diff,

> Original Estimate: 20m
> Remaining Estimate: 20m

> Load averages could be useful in scheduling. This patch looks to extend the
> existing Linux resource plugin (via /proc/loadavg file) to allow transmitting
> load averages of the last one minute via the TaskTrackerStatus.
> Patch is up for review, with test cases added, at:
> https://reviews.apache.org/r/20/
