Robert Kanter updated YARN-4126:
--------------------------------
Hadoop Flags: Incompatible change,Reviewed (was: Reviewed)
Release Note: Yarn now only issues and allows delegation tokens in secure
clusters. Clients should no longer request delegation tokens in a non-secure
cluster, or they'll receive an IOException.
I've also marked this as incompatible and put something in the Release Note
field. I'll also close YARN-5750.
> RM should not issue delegation tokens in unsecure mode
