HA: Client support for getting delegation tokens to an HA cluster
-----------------------------------------------------------------
Key: HDFS-2904
URL: https://issues.apache.org/jira/browse/HDFS-2904
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha, hdfs client, name-node, security
Affects Versions: HA branch (HDFS-1623)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
Currently we have server-side support for delegation tokens in HA, and some
tests to verify it, but the client throws NPEs when trying to fetch a DT. This
is because the cluster doesn't have a single hostname, but instead a logical
nameservice name.
