> Issue Type: Sub-task
> Components: Cluster Management
> Reporter: Kurt Young
> Assignee: zhangjing
>
> There are mainly 3 logics initiated from RM to TM:
> * Heartbeat, RM use heartbeat to sync with TM's slot status
> * SlotRequest, when RM decides to assign slot to JM, should first try to send
> request to TM for slot. TM can either accept or reject this request.
> * FailureNotify, in some corner cases, TM will be marked as invalid by
> cluster manager master(e.g. yarn master), but TM itself does not realize. RM
> should send failure notify to TM and TM can terminate itself
