Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: jobtracker
Affects Versions: 0.22.0
Environment: GNU/Linux
Reporter: Harsh J Chouraria
Assignee: Harsh J Chouraria
Priority: Minor
Fix For: 0.22.0
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:
