Project: Apache HAWQ

mode resource broker failed to get YARN queue report of queue default.
LibYarnClient::getQueueInfo, Catch the Exception:LibYarnClient::libyarn AM
heartbeat thread has stopped.",,,,,,,0,,"resourcebroker_LIBYARN_proc.c",1840,
resource broker process should re-register HAWQ to YARN in this case, but
actually not.
The reason is:
In function handleRM2RB_GetClusterReport(), when RB2YARN_getQueueReport()
failed, function sendRBGetClusterReportErrorData() is called, but
sendRBGetClusterReportErrorData() returns OK(should return RESBROK_ERROR_GRM)
