I am writing test case for this fix and will upload a patch soon.

> Today we are not validating certain configuration parameters set in
> yarn-site.xml. 1) Configurations related to paths... such as local-dirs,
> log-dirs.. Our NM crashes during startup if they are set to relative paths
> rather than absolute paths. To avoid such failures we can enforce checks
> (absolute paths) before startup . i.e. before we actually startup...( i.e.
> directory handler creating directories).
> 2) Also for all the parameters using "hostname:port" unless we are ok with
> default port.
