[jira] [Commented] (YARN-4781) Support intra-queue preemption for fairness ordering policy.

    [ https://issues.apache.org/jira/browse/YARN-4781?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15187482#comment-15187482 ] 

Sunil G commented on YARN-4781:
-------------------------------

Hi [~leftnoteasy]
Trying to understand the context here, current PCPP is trying to preempt intra-queue preemption if one/more queues are under served. This is when we use policies such as Fifo or Fair. With this new ordering policy, will this be handled by scheduler itself while allocation time? Could you pls help to share some details.
