Daryn Sharp commented on HADOOP-10016:
--------------------------------------
I don't understand the need for an artificial token. Servers are supposed to
return null if asked for a token but they don't support tokens. The token
acquisition handles this unless bugs were introduced.
> Distcp should support copy from a secure Hadoop 1 cluster to an insecure
> Hadoop 2 cluster
