--------------------------------
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.
