Daryn Sharp commented on HDFS-2473:
-----------------------------------
Tom White recently added some really neat token identifier decoding to make a
stringified token display more info. Please replace {{+
DelegationTokenIdentifier.stringifyToken(token)}} with {{+ token}} so we can
take advantage of this feature.

> Retrieving tokens from an insecure cluster throws an NPE. This prevents
> copies from insecure to secure clusters. The problem is in
> {{DFSClient.getDelegationToken()}}. It attempts to set the service and log
> the token w/o a null check.
> FetchDT will also throw exceptions when fetching tokens from an insecure
> cluster.
