[jira] [Created] (HAWQ-344) When resource queue capacity is shrunk, deadlock detection maybe not triggered

Amy created HAWQ-344:
------------------------

             Summary: When resource queue capacity is shrunk, deadlock detection maybe not triggered
                 Key: HAWQ-344
                 URL: https://issues.apache.org/jira/browse/HAWQ-344
             Project: Apache HAWQ
          Issue Type: Bug
          Components: Resource Manager
            Reporter: Amy
            Assignee: Lei Chang


It maybe an unsigned integer problem. When resource queue capacity is shrunk, the waiting requests' vseg capacity is bigger than the real capacity, so that the  D-value will be a negative number, then type of variable uint32 will turn the negative number to a big positive number.
