[jira] Created: (HDFS-994) Provide methods for obtaining delegation token from Namenode for hftp and other uses

Provide methods for obtaining delegation token from Namenode for hftp and other uses
------------------------------------------------------------------------------------

                 Key: HDFS-994
                 URL: https://issues.apache.org/jira/browse/HDFS-994
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Jakob Homan
            Assignee: Jakob Homan


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.
