>                 URL: https://issues.apache.org/jira/browse/SPARK-42880
>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core, YARN
>    Affects Versions: 3.3.2
>            Reporter: Zhifang Li
>            Priority: Minor
>
> Since Spark3.3 has changed log4j1 to log4j2, some documents should also be updated. 
> For example, docs/running-on-yarn.md still uses log4j1 syntax as follows.
> `log4j.appender.file_appender.File=${spark.yarn.app.container.log.dir}/spark.log`.
