Hi all, I happened to review some PRs and I noticed that some configurations don't have some information necessary.
To be explicit, I would like to make sure we document the direct relationship between other configurations in the documentation. For example, `spark.sql.adaptive.shuffle.reducePostShufflePartitions.enabled` can be only enabled when `spark.sql.adaptive.enabled` is enabled. That's clearly documented. We're good in general given that we document them in general in Apache Spark. See 'spark.task.reaper.enabled', 'spark.dynamicAllocation.enabled', 'spark.sql.parquet.filterPushdown', etc. However, I noticed such a pattern that such information is missing in some components in general, for example, `spark.history.fs.cleaner.*`, `spark.history.kerberos.*` and `spark.history.ui.acls.* ` I hope we all start to document such information. Logically users can't know the relationship and I myself had to read the codes to confirm when I review. I don't plan to document this officially yet because to me it looks a pretty logical request to me; however, let me know if you guys have some different opinions. Thanks.
