Jian He created HADOOP-10519: -------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
