                 Key: HDFS-1023
                 URL: https://issues.apache.org/jira/browse/HDFS-1023
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Jakob Homan
            Assignee: Jakob Homan


Currently limitations in Sun's KerbSSL implementation require the https server to be run as "host/[machine]@realm." and another Sun KerbSSL limitation appears to require you to store all principals in the same keytab, meaning fully functional, secured Namenodes require combined keytabs.  However, it may be that one wishes to run a namenode without a secondary namenode or other utilities that require https.  In this case, we should allow the http server to start and log a warning that it will not be able to accept https connections.
