> 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.
