---------------------------------------------

             Summary: Attempt-failures validatiy interval should have a global admin configurable
lower limit
                 Key: YARN-3669
                 URL: https://issues.apache.org/jira/browse/YARN-3669
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli


Found this while reviewing YARN-3480.

bq. When 'attemptFailuresValidityInterval'(introduced in YARN-611) is set to a small value,
retried attempts might be very large. So we need to delete some attempts stored in RMStateStore
and RMStateStore.
I think we need to have a lower limit on the failure-validaty interval to avoid situations
like this.

Having this will avoid pardoning too-many failures in too-short a duration.
