Mahadev konar commented on HDFS-2904:
-------------------------------------
I didnt look at the patch very closely but having the RM deploy all the HA NN
configs in the interim seems ok. Though having a comma separated list of
hostnames in the DT would have eliminated the need. Todd, about the client not
knowing all the hosts, it should be able to get all the hosts even when you use
ZK, no?

> Components: ha, hdfs client, name-node, security
> Affects Versions: HA branch (HDFS-1623)

> 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.
