>
> Key: AMBARI-21232
> URL: https://issues.apache.org/jira/browse/AMBARI-21232
> Project: Ambari
> Issue Type: Improvement
> Components: ambari-views
> Affects Versions: 2.4.0
> Reporter: Sridhar Sailappan
> Assignee: Madhuvanthi Radhakrishnan
> Priority: Major
> Fix For: 3.1.0
>
> Attachments: Patch_AmbariViewUtils_WebHDFS.txt
>
>
> In Ambari View Utils , the determination logic for the value of defaultFS
> when WebHDFS is enabled, needs to consider the current property value of
> defaultFS. Please see attached patch for the context.
> If the existing configuration for the defaultFS URI already has the protocol
> specified as webhdfs or swebhdfs, the URI should be used as provided and a
> new value should not be constructed. Constructing a new value in a such a
> scenario may lead to unexpected behavior if the Namenode has different
> host-port settings for the HTTP and WebHDFS access.
> The patch also addresses the following code cleanup:
> 1) Fix variable names httpAddr and httpsAddr (current implementation has
> the naming interchanged)
> 2) Add null value check for httpAddr before assignment to hostWithPort
> 3) Fix typo in variable names - DFS_NAMENODE_HTTP_ADDRESS and
> DFS_NAMENODE_HTTPS_ADDRESS
