Gabor Somogyi commented on SPARK-24621:
---------------------------------------
I've analyzed through this issue with the latest master branch and here are my
findings:
* Steps what I've done:
https://gist.github.com/gaborgsomogyi/03bade548902f74cac7d0962f76c76f1
* Secure master/worker/spark-shell connection works fine
* On the spark master webpage "Workers" section -> "Worker Id" field is
pointing to an URL where scheme not added (so http) and port is 8080 (http port)
* On the spark master webpage "Running Applications" section -> "Name" field is
pointing to an URL where scheme not added (so http) and port is 4040 (http port)
In both cases when one clicks on the mentioned unsecure links the request
forwarded to the secure page.
Please see the functionality
[here|https://github.com/apache/spark/blob/3fcbc7fb9f7b58b040a85289a82cf551d51bac37/core/src/main/scala/org/apache/spark/ui/JettyUtils.scala#L328].
>From my perspective it's more like a cosmetic change than a heavy bugfix.
[~toopt4] I think the commented fix is just bad because boundPort is pointing
to the http port but in secure case securePort has to be used.

> ApplicationID correctly points to DNS url

> Update: I found setting SPARK_PUBLIC_DNS to DNS hostname will make Name point
