[jira] [Created] (YARN-514) Delayed store operations should not result in RM unavailability for app submission

Bikas Saha created YARN-514:
-------------------------------

             Summary: Delayed store operations should not result in RM unavailability for app submission
                 Key: YARN-514
                 URL: https://issues.apache.org/jira/browse/YARN-514
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bikas Saha
            Assignee: Bikas Saha


Currently, app submission is the only store operation performed synchronously because the app must be stored before the request returns with success. This makes the RM susceptible to blocking all client threads on slow store operations, resulting in RM being perceived as unavailable by clients.
