             Summary: Log count of different events if eventQueue has lot of 
events
                 Key: TEZ-2316
                 URL: https://issues.apache.org/jira/browse/TEZ-2316
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rohini Palaniswamy
            Assignee: Bikas Saha


  The default heart beat interval is 100ms which is a poor configuration for 
very big jobs and could lead to event queue quickly filling up. Logging number 
of events and it types once it crosses a threshold (For eg: every 
200K/400K/600K, etc) will at least help see the problem while debugging.
