Haohui Mai commented on HDFS-5122:
----------------------------------

I've created a new JIRA to track the status of the fail-over mechanism in WebHDFS:

> You have to provide the exact active namenode hostname. On an HA cluster using dfs client
one should not need to provide the active nn hostname
