Arun Suresh commented on YARN-1014: ----------------------------------- Thanks for taking this up [~kasha].. Id think this would be generally useful in trunk, but w.r.t YARN-2877, We were actually planning on getting the ContainersMonitor to kill/preempt opportunistic containers. This way, we can probably have more control over which containers are to be killed.
