Zachary Blanco updated AMBARI-12763:
------------------------------------
Description:
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
