Hi there, It’s true that the preponderance of log4j 1.2.x in many existing live projects is kind of a pain in the butt.
But there is a solution. 1. Migrate all Spark code to use slf4j APIs; 2. Exclude log4j 1.2.x from any dependencies sucking it in; 3. Include the log4j-over-slf4j bridge jar and slf4j-api jars; 4. Choose your favourite modern logging implementation and add it as a “runtime" dependency together with it’s slf4j binding jar (if needed). In fact in the short term you can replace steps 1 and 2 with "remove the log4j 1.2.17 jar from the distribution" and it should still work. The slf4j project also includes a commons-logging shim for capturing its output too. FWIW, the slf4j project is run by one of the original log4j developers.

I tried and failed to upgrade it a couple years ago. you are welcome to try, and open a PR if successful.

I see that the spark log4j version is very old(1.2.17) and it does not support JSON logs over tcp sockets on containers. I wanted to konw what is the plan for upgrading the log4j version to log4j2.
