[jira] [Created] (YARN-8657) User limit calculation should be read-lock-protected within LeafQueue

Wangda Tan created YARN-8657:
--------------------------------

             Summary: User limit calculation should be read-lock-protected within LeafQueue
                 Key: YARN-8657
                 URL: https://issues.apache.org/jira/browse/YARN-8657
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacity scheduler
            Reporter: Sumana Sathish
            Assignee: Wangda Tan


When async scheduling is enabled, user limit calculation could be wrong: 

It is possible that scheduler calculated a user_limit, but inside {{canAssignToUser}} it becomes staled. 

We need to protect user limit calculation.
