LuciferYang opened a new pull request, #37853: URL: https://github.com/apache/spark/pull/37853
### What changes were proposed in this pull request? From the context from [pr](https://github.com/apache/spark/pull/19032) of [SPARK-17321](https://issues.apache.org/jira/browse/SPARK-17321), `YarnShuffleService` will persist data into `Level/RocksDB` when Yarn NM recovery is enabled. This behavior is not controlled by `spark.shuffle.service.db.enabled` and is not always enabled. So the description of `spark.shuffle.service.db.enabled` in `spark-standalone.md` is misleading. This pr deletes the part related to yarn in the description of `spark.shuffle.service.db.enabled`, and adds the precondition description related to `Yarn NodeManager recovery is enabled` for `spark.shuffle.service.db.backend`. ### Why are the changes needed? Fix document description. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Pass GitHub Actions -- This is an automated message from the Apache Git Service.
