Subject [jira] [Created] (HDFS-6312) WebHdfs HA failover is broken on secure clusters
Date Wed, 30 Apr 2014 15:48:17 GMT
Daryn Sharp created HDFS-6312:
---------------------------------

             Summary: WebHdfs HA failover is broken on secure clusters
                 Key: HDFS-6312
                 URL: https://issues.apache.org/jira/browse/HDFS-6312
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: webhdfs
    Affects Versions: 2.4.0, 3.0.0
            Reporter: Daryn Sharp
            Priority: Blocker


When webhdfs does a failover, it blanks out the delegation token.  This will cause subsequent
operations against the other NN to acquire a new token.  Tasks cannot acquire a token (no
kerberos credentials) so jobs will fail.
