-------------------------------
I believe YARN-713 fixed this.
> RM shutdown due to java.net.UnknownHostException

> Key: YARN-1894
> URL: https://issues.apache.org/jira/browse/YARN-1894
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Reporter: Mohammad Kamrul Islam
> Assignee: Mohammad Kamrul Islam

> Background:
> ----------------
> I started Hadoop 2.3 on my Mac in my office network and submitted few jobs
> successfully. When i went to my home (new network), I submitted another job
> and it abruptly pulled down the RM service.
> Error in RM log:

> Proposal:
> ---------------
> I believe the root cause : I moved my machine from one network to another
> with the same RM service.
> My point is: Whatever the cause, RM is a long running core-service and it
> should not exit this way. An appropriate error message should be sufficient.
> If there is an consensus (or no disagreement), I can work for a patch.
