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.
