> 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
