Yi Jin created HAWQ-357:
---------------------------

             Summary: Track how many times a segment can not get expected containers from global resource manager
                 Key: HAWQ-357
                 URL: https://issues.apache.org/jira/browse/HAWQ-357
             Project: Apache HAWQ
          Issue Type: Improvement
          Components: Resource Manager
            Reporter: Yi Jin
            Assignee: Lei Chang


This improvement makes HAWQ RM able to track the times one segment can not get expected containers from global resource manager, YARN for example. 

In some cases, another YARN application may hold containers without returning them in time, HAWQ RM may always find some segments having no resource. This improvement make HAWQ RM log this situation as a warning.
