This jira is created to implement it at > the parent queue as well. > It involves : > 1. Making "check for fair share starvation" and "amount of resource to > preempt" recursive such that they traverse the queue hierarchy from root to > leaf. > 2. Currently fairSharePreemptionTimeout is a global config. We could make it > configurable on a per queue basis,so that we can specify different timeouts > for parent queues. -- This message was sent by Atlassian JIRA (v6.2#6252)
