(Updated June 11, 2013, 9:42 p.m.) Review request for mesos. Changes ------- Rebasing on master. Description ------- Don't prematurely kill TaskTrackers. We assign the JobID to the internal Mesos tracker (for the TaskTracker) rather than the TaskID. In the case where a TaskTracker has only map tasks assigned to it and they have all completed, we mustn't terminate the tracker until the entire job has finished, including the map tasks.
