> When RM restarts, it will recover RMAppAttempts and registry them to 
> AMLivenessMonitor if they are not in final state. AM will time out in RM if 
> the recover process takes long time due to some reasons(e.g. too many apps). 
> In our system, we found the recover process took about 3 mins, and all AM 
> time out.
