Owen O'Malley commented on HADOOP-7625:
---------------------------------------
I don't think there is currently a case where a token will have a non-null
renewer when setKind is called, but it could.
When isManaged, renew or cancel are called on a token, it first calls
getRenewer. getRenewer returns the renewer field, if it is set or otherwise it
finds the right kind of renewer based on the kind. When you change the kind,
generally the discovered renewer will be different. Therefore, to avoid
accidentally using the wrong renewer, it is safer to clear it when we set the
kind.
