> In the Apache Knox service screen > configuration > advanced topology the templating/macros used does automatically add multiple namenode URLs if WebHDFS HA is enabled.
> We should changed the template from
> <url>http://{{namenode_host}:{{namenode_port}}webhdfs</url>
> to something that's simple like:
> {{webhdfs_service_urls}}
> This will automatically add URLs if there are multiple namenodes - thus allowing one less step for setting up HA for WebHDFS in Knox
