To use a custom log4j configuration for the application master or executors, there are two options:
-- upload a custom log4j.properties using spark-submit, by adding it to the "--files" list of files
+- upload a custom `log4j.properties` using `spark-submit`, by adding it to the `--files` list of files
to be uploaded with the application.

Note that for the first option, both executors and the application master will share the same
log4j configuration, which may cause issues when they run on the same node (e.g. trying to write
to the same log file).
-If you need a reference to the proper location to put log files in the YARN so that YARN can properly display and aggregate them, use "${spark.yarn.app.container.log.dir}" in your log4j.properties. For example, log4j.appender.file_appender.File=${spark.yarn.app.container.log.dir}/spark.log. For streaming application, configuring RollingFileAppender and setting file location to YARN's log directory will avoid disk overflow caused by large log file, and logs can be accessed using YARN's log utility.
