--------------------------------

Thanks [~yufeigu], YARN-6061 is very useful to handle critical thread exit, for dead locks
we use ThreadMxBean to detect.

> RM may becomes unhealthy but still alive,  for example scheduling thread exit, dead lock
happens.  seems useful to add a healthy checker service, if check failed, let RM exit
