Subject [jira] [Commented] (HDFS-11691) Add a proper scheme to the datanode links in NN web UI
Date Mon, 24 Apr 2017 14:57:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15981295#comment-15981295

Kihwal Lee commented on HDFS-11691:

bq. 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?
Yes, I saw that during testing.  I think that's acceptable or may even be preferable.

> 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.
