[jira] [Created] (HDFS-6312) WebHdfs HA failover is broken on secure clusters

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.
