> YARN-654 performs sanity checks for parameters of public methods in AMRMClient. Those
may create runtime exception. 
> Currently, heartBeat thread in AMRMClientAsync only captures IOException and YarnException,
and will not handle Runtime Exception properly. 
> Possible solution can be: heartbeat thread will catch throwable and notify the callbackhandler
thread via existing savedException
