Re: Requesting containers on a specific host
Hi Devaraj,

   Thanks for pointing me to this RC. I am trying this out, and getting
this error for NM to get started. My RM is running fine, but NM is failing
and saying that it is disallowed by RM and received a SHUTDOWN message.
Please give me clue to resolve this.
