While HAWQ with yarn mode is running, sometimes the heartbeat thread of libyarn maybe fail(e.g. YARN RM restarts) and quit,

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)
