-----------------------------------
Summary: FairScheduler: add global flag to disable AM-preemption
Key: YARN-10625
URL: https://issues.apache.org/jira/browse/YARN-10625
Project: Hadoop YARN
Issue Type: Improvement
Components: fairscheduler
Affects Versions: 3.3.0
Reporter: Peter Bacsko
Assignee: Peter Bacsko
YARN-9537 added a feature to disable AM preemption on a per queue basis.
This is a nice enhancement, but it's very inconvenient if the cluster has a lot
of queues or queues dynamically created/deleted regularly (static queue
configuration changes).
It's a legitimate use-case to have AM preemption turned off completely. To make
it easier, add property which acts as a global flag for this feature.
