### What changes were proposed in this pull request? This PR aims to enable `spark.eventLog.compress` by default for Apache Spark 4.0.0. ### Why are the changes needed? - To save the event log storage cost by compressing the logs with ZStandard codec by default ### Does this PR introduce _any_ user-facing change? Although we added a migration guide, the old Spark history servers are able to read the compressed logs. ### How was this patch tested? Pass the CIs. ### Was this patch authored or co-authored using generative AI tooling? No. Closes apache#43036 from dongjoon-hyun/SPARK-45257.

### What changes were proposed in this pull request? Add `Spark History Server` example. ### Why are the changes needed? Since Apache Spark 4.0, Spark rolls the event logs by default and compressed them by default. - apache/spark#43638 - apache/spark#43036 However, we still need more configurations to allow SHS manages the event log directories. This PR aims to provide an example of `Spark History Server` with the configuration. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Manual review. ### Was this patch authored or co-authored using generative AI tooling? No. Closes #249 from dongjoon-hyun/SPARK-52481. Authored-by: Dongjoon Hyun <[email protected]> Signed-off-by: Dongjoon Hyun <[email protected]>
