---------------------------------------
Summary: Adding Support for WebHDFS HA mode in Knox Configuration
Key: AMBARI-12763
URL: https://issues.apache.org/jira/browse/AMBARI-12763
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Affects Versions: 2.1.2
Reporter: Zachary Blanco
Priority: Minor
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 this:
{{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
