Daryn Sharp commented on HDFS-6329:
-----------------------------------
You may want to remove this line {{LOG.info("KLKL uri = " + uri);}}. :)
Maybe I missed it, but a test cast to simulate our HA IP-failover would be
invaluable to preventing another regression.
> WebHdfs does not work if HA is enabled on NN but logical URI is not
> configured.

> After HDFS-6100, namenode unconditionally puts the logical name (name service
> id) as the token service when redirecting webhdfs requests to datanodes, if
> it detects HA.
> For HA configurations with no client-side failover proxy provider (e.g. IP
> failover), webhdfs does not work since the clients do not use logical name.
