Alex Bozarth commented on SPARK-21838:
--------------------------------------
Given the behavior on master is as you described I would recommend either
adding a 404 or redirect functionality to the master branch rather than trying
to port the feature that fixed the bug back to 2.1.0 or 2.2.0
> "Completed Applications" links not always working in cluster with
> spark.ui.reverseProxy=true

> Key: SPARK-21838
> URL: https://issues.apache.org/jira/browse/SPARK-21838
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 2.1.0, 2.2.0
> Environment: Spark Cluster with reverse proxy enabled:
> spark.ui.reverseProxyUrl=http://127.0.1.1:8080/
> spark.ui.reverseProxy=true
> Reporter: Ingo Schuster
>
> 1. Using a Spark Cluster with reverse Proxy enabled, web UI is at:
> http://127.0.0.1:8080/
> 2, Starting an application and enter the application specific web UI (by
> clicking on the application name):
> http://127.0.0.1:8080/proxy/app-20170825151733-0001/jobs/
> 3. If you click on any link (e.g. on the "Executors") +after the application
> has terminated+, the Spark master UI will be served again, howeverthis is
> done under the URL of the executors page:
> http://127.0.0.1:8080/proxy/app-20170825151733-0001/executors/
> 4. When you now click on the link to the just completed application, nothing
> happens (you stay on the master web UI home page):
> http://127.0.0.1:8080/proxy/app-20170825151733-0001/executors/app?appId=app-20170825151733-0001
> Problem is that in step 3, we cannot serve the applications executors page
> since it already terminated. Falling back to the master web UI home page is
> ok, but it should be done with an http redirect to that the relative URLs on
> the master home page are build with the correct base URL.
