Spark UI - Bug Executors tab when using proxy port

2023-07-06 Thread Bruno Pistone
Hello everyone,

I’m really sorry to use this mailing list, but seems impossible to notify a 
strange behaviour that is happening with the Spark UI. I’m sending also the 
link to the stackoverflow question here 
https://stackoverflow.com/questions/76632692/spark-ui-executors-tab-its-empty

I’m trying to run the Spark UI on a web server. I need to configure a specific 
port for running the UI and a redirect URL. I’m setting up the following OPTS:

```
export SPARK_HISTORY_OPTS="-Dspark.history.fs.logDirectory=${LOCAL_PATH_LOGS}
-Dspark.history.ui.port=18080 
-Dspark.eventLog.enabled=true 
-Dspark.ui.proxyRedirectUri=${SERVER_URL}"

./start-history-server.sh
``

What is happening: The UI is accessible through the url 
https://${SERVER_URL}/proxy/18080 

When I’m selecting an application and I’m clicking on the tab “Executors”, it 
remains empty. By looking at the API calls done by the UI, I see there is the 
"/allexecutors” which returns 404.

Instead of calling 
https://${SERVER_URL}/proxy/18080/api/v1/applications/${APP_ID}/allexecutors 

I see that the URL called is 
https://${SERVER_URL}/proxy/18080/api/v1/applications/18080/allexecutors 


Seems that the appId is not correctly identified. Can you please provide a 
solution for this, or an estimated date for fixing the error?

Thank you,
