Ambud Sharma commented on MAPREDUCE-2170: ----------------------------------------- Hi, I am wondering if keeping that(systemaverageload) as a separate RPC call used/made when need would make more sense? -Ambud > Send out last-minute load averages in TaskTrackerStatus > ------------------------------------------------------- > > 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 > Reporter: Harsh J > Assignee: Harsh J > Priority: Critical > Fix For: 0.24.0 > > Attachments: mapreduce.loadaverage.r3.diff, > mapreduce.loadaverage.r4.diff, mapreduce.loadaverage.r5.diff, > mapreduce.loadaverage.r6.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/ -- This message is automatically generated by JIRA.
