[jira] [Created] (HIVE-15541) Hive OOM when ATSHook enabled and ATS goes down

Jason Dere created HIVE-15541:
---------------------------------

             Summary: Hive OOM when ATSHook enabled and ATS goes down
                 Key: HIVE-15541
                 URL: https://issues.apache.org/jira/browse/HIVE-15541
             Project: Hive
          Issue Type: Bug
          Components: Hooks
            Reporter: Jason Dere
            Assignee: Jason Dere


The ATS API used by the Hive ATSHook is a blocking call, if ATS goes down this can block the ATSHook executor, while the hook continues to submit work to the executor with each query.
Over time the buildup of queued items can cause OOM.
