Subject [jira] [Commented] (HDFS-11691) Add a proper scheme to the datanode links in NN web UI
Date Mon, 24 Apr 2017 14:50:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15981281#comment-15981281

Weiwei Yang commented on HDFS-11691:

Hi [~kihwal]

Thanks for catching and fixing this. I have one small comment here

+    <td ng-value="{state}-{name}"><a href='{dnWebAddress}'>{dnWebAddress}</a></td>

this way datanode link field on UI will also display {{http://datanodehost:port}} instead
of {{datanodehost:port}}, this look&feel change will be OK right?

> On the datanodes page of the namenode web UI, the datanode links may not be correct if
the namenode is serving the page through http but https is also enabled.  This is because
{{dfshealth.js}} does not put a proper scheme in front of the address.  It already determines
whether the address is non-secure or secure. It can simply prepend {{http:}} or {{https:}}
to what it is currently setting.
> The existing mechanism would work for YARN and MAPRED, since they can only serve one
protocol, HTTP or HTTPS.
