Description
As part of addressing HUDI-4441, we've erroneously rebased Hudi onto "log4j-1.2-api" module under impression that it's an API module (as advertised) which turned out not to be the case: it's actual bridge implementation, requiring Log4j2 be provided on the classpath as required dependency.
For version of Spark < 3.3 this triggers exceptions like the following one (reported by akmodi)
