> In YARN-Federation mode, once a SubCluster is registered, the SubCluster is 
> always in the RUNNING state, even if the SubCluster has no heartbeat for a 
> long time.
> We will let the Router automatically check the heartbeat time of the 
> SubCluster, and once the heartbeat exceeds 30mins, we will set the SubCluster 
> to the SC_LOST state.
