In securre clusters, NN and SNN should verify that the remote principal during image and edits
transfer
-------------------------------------------------------------------------------------------------------

                 Key: HDFS-1033
                 URL: https://issues.apache.org/jira/browse/HDFS-1033
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: security
            Reporter: Jakob Homan
            Assignee: Jakob Homan


Currently anyone can connect and download image/edits from Namenode.  In a secure cluster
we can verify the identity of the principal making the request; we should disallow requests
from anyone except the NN and SNN principals (and their hosts due to the lousy KerbSSL limitation).
