[jira] [Created] (YARN-10591) Allow USERLIMIT_FIRST as only valid
configuration when FairOrdering is used
VADAGA ANANYO RAO created YARN-10591:
----------------------------------------
Summary: Allow USERLIMIT_FIRST as only valid configuration when FairOrdering is used
Key: YARN-10591
URL: https://issues.apache.org/jira/browse/YARN-10591
Project: Hadoop YARN
Issue Type: Improvement
Components: capacity scheduler
Reporter: VADAGA ANANYO RAO
Assignee: VADAGA ANANYO RAO
When FairOrderingPolicy is being used in CapacityScheduler, we should only allow for USERLIMIT_FIRST.
The alternate option to USERLIMIT_FIRST is PRIORITY_FIRST. However, application priorities create anti-patterns with fairness. So we should not allow for PRIORITY_FIRST to be set.
This Jira is to add validation check to ensure only USERLIMIT_FIRST is set if FairOrderingPolicy is being used.
