Due to log4j vulnerability issue I have migrated from log4j1.2.17 to log4j2.17.1 in my spark-2.4.0-bin-hadoop2.7 .
i have removed the log4j files in jar path log4j-1.2.17.jar,slf4j-log4j12-1.7.16.jar(removed) and i have placed the new log4j2.17.1 jar files log4j-api-2.17.1.jar;log4j-core-2.17.1.jar;log4j-slf4j-impl-2.17.1.jar;log4j-1.2-api-2.17.1.jar
after i have restarted my master and slaves
