Nigel Daley commented on MAPREDUCE-2170:
----------------------------------------
Sorry for the long precommit comment by Hadoop QA. I'm trying to get this
running on MR again. Lots of tests failing. Looks like trunk wasn't properly
updated after 0.22 branching. I still see references to 0.22 in the
ivy/libraries.properties file on trunk.

> 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:
