Dongjin Lee commented on KAFKA-13547:
-------------------------------------
[~masood31] I am currently working on a preview version based on AK 2.8.1 and
3.0.0, and I will complete it in this weekend. It will replace all log4j 1.x
dependency into 2.x, with backward compatibility of logger configuration.
+1. I can't guarantee when it will be merged into the official release.
