      Description

      After failover, RM may require a certain threshold to determine whether it’s safe to make scheduling decisions and start accepting new container requests from AMs. The threshold could be a certain amount of nodes. i.e. RM waits until a certain amount of nodes joining before accepting new container requests. Or it could simply be a timeout, only after the timeout RM accepts new requests.
      NMs joined after the threshold can be treated as new NMs and instructed to kill all its containers.
