Subject [jira] [Created] (HADOOP-13206) Delegation token cannot be fetched and used by different versions of client

----------------------------------

             Summary: Delegation token cannot be fetched and used by different versions of
client
                 Key: HADOOP-13206
                 URL: https://issues.apache.org/jira/browse/HADOOP-13206
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
    Affects Versions: 2.6.1, 2.3.0
            Reporter: Zhe Zhang
            Assignee: Zhe Zhang


We have observed that an HDFS delegation token fetched by a 2.3.0 client cannot be used by
a 2.6.1 client, and vice versa. Through some debugging I found that it's a mismatch between
the token's {{service}} and the {{service}} of the filesystem (e.g. {{webhdfs://host.something.com:50070/}}).
One would be in numerical IP address and one would be in non-numerical hostname format.
