Chris Riccomini commented on MAPREDUCE-4672:
--------------------------------------------
Ahhh, I see. So I should use the mapred AM as an example of how to gracefully
shut down in the case where the AM is running with no NM? The AMResponse will
denote that I should shut down:
getReboot()
Should the ApplicationMaster reboot for being horribly out-of-sync
with the ResourceManager as deigned by getResponseId()?
Thanks, I'll use this.

> Hey Guys,
> I'm running a 9 node cluster with 8 NMs and a single RM node. If I run an app
> master and have that app master start a container, then shut down all NMs,
> but leave the RM up (to simulate a failure), the containers timeout and fail,
> as expected.
> What's unexpected is that my log then starts filling with:
