-------------------------------------
Summary: Support customized log url for Spark UI and History
server in Kubernetes environment
Key: SPARK-49149
URL: https://issues.apache.org/jira/browse/SPARK-49149
Project: Spark
Issue Type: Improvement
Components: UI
Affects Versions: 3.4.3
Reporter: Yichuan Huang
Fix For: 4.0.0, 3.5.3
Spark provides two configs to alternate the log url on the live UI and history
server, `spark.ui.custom.executor.log.url` and
`spark.history.custom.executor.log.url`. The configs support path variables
which will be replaced at runtime, but currently this only works on Yarn.
Running on k8s with the path variable doesn't work. Here's an example
```
./bin/spark-shell --conf
spark.ui.custom.executor.log.url="URL_PREFIX?appId=\{{APP_ID}}&execId=\{{EXECUTOR_ID}}"
```
The log column doesn't show up in the Spark UI, and Spark driver printing
```
24/08/07 17:23:45 INFO ExecutorLogUrlHandler: Fail to renew executor log urls:
some of required attributes are missing in app's event log.. Required:
Set(APP_ID, EXECUTOR_ID) / available: Set(). Falling back to s how app's
original log urls.
```
the empty attribute `Set()` in the above log segment indicates the feature not
supported in k8s environment, thus creating this ticket to add the support
