[jira] [Created] (YARN-5802) Application priority updates add
pending apps to running ordering policy
Bibin A Chundatt created YARN-5802:
--------------------------------------
Summary: Application priority updates add pending apps to running ordering policy
Key: YARN-5802
URL: https://issues.apache.org/jira/browse/YARN-5802
Project: Hadoop YARN
Issue Type: Bug
Reporter: Bibin A Chundatt
Assignee: Bibin A Chundatt
Priority: Critical
{{LeafQueue#updateApplicationPriority}}
{code}
getOrderingPolicy().removeSchedulableEntity(attempt);
// Update new priority in SchedulerApplication
attempt.setPriority(newAppPriority);
getOrderingPolicy().addSchedulableEntity(attempt);
{code}
We should add again to ordering policy only when attempt available in first case.Else during application attempt removal will try to iterate on killed application still available in pending Ordering policy.Which can cause RM to crash.
