    Description

      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/
