> In hftp, destination clusters will require an RPC-version-agnostic means of obtaining delegation tokens from the source cluster. The easiest method is provide a webservice to retrieve a token over http.  This can be encrypted via SSL (backed by Kerberos, done in another JIRA), providing security for cross-cluster hftp operations.
