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

             Summary: In HDFS HA mode, Distcp/SLive with webhdfs on secure cluster fails with
Client cannot authenticate via:[TOKEN, KERBEROS] error
                 Key: HADOOP-10519
                 URL: https://issues.apache.org/jira/browse/HADOOP-10519
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Jian He


Opening on [~arpitgupta]'s behalf.

We observed that, in HDFS HA mode, running Distcp/SLive with webhdfs will fail on YARN.  In
non-HA mode, it'll pass. 

The reason is in HA mode, only webhdfs delegation token is generated for the job, but YARN
also requires the regular hdfs to do localization, log-aggregation etc.
In non-HA mode, both tokens are generated for the job.
