[jira] [Commented] (MAPREDUCE-3602) Add Preemption to MR2 Fair
Scheduler
Posted by "Patrick Wendell (Commented) (JIRA)" <ji...@apache.org>.

Patrick Wendell commented on MAPREDUCE-3602:
--------------------------------------------
The MR2 node update API already has hooks for the RM to tell the NM to release containers. Are there any problems using this method to preempt containers? I.e. will application masters handle unexpected container disruption gracefully or are there other considerations if we want the scheduler to preempt?
