> 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.
