[jira] [Created] (HIVE-19430) ObjectStore.cleanNotificationEvents OutOfMemory on large number of pending events

Thejas M Nair created HIVE-19430:
------------------------------------

             Summary: ObjectStore.cleanNotificationEvents OutOfMemory on large number of pending events
                 Key: HIVE-19430
                 URL: https://issues.apache.org/jira/browse/HIVE-19430
             Project: Hive
          Issue Type: Bug
            Reporter: Thejas M Nair
            Assignee: Thejas M Nair


If there are large number of events that haven't been cleaned up for some reason, then ObjectStore.cleanNotificationEvents() can run out of memory while it loads all the events to be deleted.
It should fetch events in batches.
