This changes allows users to introduce log configuration using spark log4j2. This is important because Spark 3.3 onwards migrate from Log4j 1.x, and that Log4j 1.x has reached end of life. Below a snippet from [Spark core migration guide](https://spark.apache.org/docs/latest/core-migration-guide.html#upgrading-from-core-32-to-33): > Since Spark 3.3, Spark migrates its log4j dependency from 1.x to 2.x because log4j 1.x has reached end of life and is no longer supported by the community. Vulnerabilities reported after August 2015 against log4j 1.x were not checked and will not be fixed. Users should rewrite original log4j properties files using log4j2 syntax (XML, JSON, YAML, or properties format). Spark rewrites the conf/log4j.properties.template which is included in Spark distribution, to conf/log4j2.properties.template with log4j2 properties format.
