> 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.
