-------------------------------------
Summary: QueueMetrics for observe only preemption
Key: YARN-9919
URL: https://issues.apache.org/jira/browse/YARN-9919
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Prashant Golash
There should be a way to track how many containers will be preempted if
preemption is enabled in "observe only" mode.
In the case of lazy preemption, it could be bit involved as the scheduler makes
the decision.
