Robert Joseph Evans updated YARN-515:
-------------------------------------

    Attachment: YARN-515.txt

There is a unit test included that shows the problem.

> The Null pointer exception just keeps repeating and all of the nodes end up being lost.  It looks like it never gets the secret key when it registers.
