[jira] [Comment Edited] (YARN-5216) Expose configurable preemption
policy for OPPORTUNISTIC containers running on the NM
[ https://issues.apache.org/jira/browse/YARN-5216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15738832#comment-15738832 ]

I will wait for [~asuresh] to clarify here, but I think one thing on the table is to add a preempt API in container executor, which has a knob to allow KILL vs PAUSE. I captured some concerns with that, but do agree that we don't need two params - one in scheduler and other in executor.

> Currently, the default action taken by the QueuingContainerManager, introduced in YARN-2883, when a GUARANTEED Container is scheduled on an NM with OPPORTUNISTIC containers using up resources, is to KILL the running OPPORTUNISTIC containers.
> This JIRA proposes to expose a configurable hook to allow the NM to take a different action.
