--------------------------------------

             Summary: Knox configs for webhdfs_service_urls do not get updated when WebHDFS HTTPS is enabled
                 Key: AMBARI-23774
                 URL: https://issues.apache.org/jira/browse/AMBARI-23774
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 2.7.0
         Environment: Issue present in HDP 2.6.4.

Checked Trunk Ambari 2.7.0 code and same issue in params_linux.py
            Reporter: Jesus Alvarez


After enabling  *dfs.http.policy* to *HTTPS_ONLY*, knox's topology will still assume WebHDFS is on HTTP.

 

Knox's Advanced Topology resolves the webHDFS URLs as:

{{ <service>}}
{{ <role>WEBHDFS</role>}}
{{ \{{webhdfs_service_urls}}}}
{{ </service>}}

 

The issue is, in ambari's knox params_linux.py, the webhdfs_service_urls will always be prefaced with *"http"*

{{webhdfs_service_urls += buildUrlElement("*http*", host, namenode_port_map[host], "/webhdfs")}}
{{else:}}
{{ webhdfs_service_urls = buildUrlElement("*http*", namenode_host, namenode_http_port, "/webhdfs")}}
