Subject [jira] [Created] (HDFS-5150) Allow per NN SPN for internal SPNEGO.
Date Fri, 30 Aug 2013 19:09:52 GMT
Kihwal Lee created HDFS-5150:
--------------------------------

             Summary: Allow per NN SPN for internal SPNEGO.
                 Key: HDFS-5150
                 URL: https://issues.apache.org/jira/browse/HDFS-5150
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Kihwal Lee
            Priority: Blocker


For more flexible configuration of HA, the SPN for NN's internal SPNEGO needs to be per-nn.
Currently the config should contain "_HOST" or configured differently per node.

This change should not change the existing behavior unless the SPN is explicitly specified
per NN under the HA configuration.
