> Only nodes in the RUNNING state are tracked by schedulers.  When a node reconnects, RMNodeImpl.ReconnectNodeTransition
tries to remove it, even if it's in the RUNNING state.  The FairScheduler doesn't guard against
this.
> I think the best way to fix this is to check to see whether a node is RUNNING before
telling the scheduler to remove it.
