--------------------------------
https://github.com/apache/spark/pull/56903
> Add a configuration to control Spark History Server log access
> --------------------------------------------------------------
>
> Key: SPARK-57786
> URL: https://issues.apache.org/jira/browse/SPARK-57786
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 4.0.0
> Reporter: iBenny
> Priority: Major
> Labels: pull-request-available
>
> After SPARK-46903, the Spark History Server process log can be accessed from
> its home page.
> Server logs may contain sensitive information, so exposing them through the
> History Server UI by default can be a security risk.
> Add the {{spark.history.ui.log.enable}} configuration, defaulting to
> {{{}false{}}}. When disabled:
> * Hide the server log link from the home page.
> * Do not register the {{/logPage}} handler.
> * Do not register the raw {{/log}} handler.
> Administrators can explicitly enable log access by setting the configuration
> to {{{}true{}}}.
