Junping Du commented on YARN-3225:
----------------------------------

bq.  If we have a constraint that we should issue graceful decommission command 
from only one RMAdmin CLI then this issue will not be a problem.
Can we have this assumption in our first phase (target to catch up 2.8)? IMO, 
Decommissioning nodes is very restrictive operation that we don't expect 
multiple could happen at the same time on a cluster. We can improve later if we 
think this is not good enough. 

> New parameter or CLI for decommissioning node gracefully in RMAdmin CLI

> New CLI (or existing CLI with parameters) should put each node on 
> decommission list to decommissioning status and track timeout to terminate 
> the nodes that haven't get finished.
