Todd Lipcon updated HDFS-2904:
------------------------------
Attachment: hdfs-2904.txt
Improved rev of the patch:
- DTs for logical URIs now include a special prefix in the service name
- if the renew code path sees this special prefix, but it doesn't have a proxy
provider configured for that logical URI, it will fail with a reasonable
message (instead of getting a strange UnknownHostException as it did before)
- more javadoc/cleanup of method names
> HA: Client support for getting delegation tokens to an HA cluster

> 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.
