Dongjin Lee commented on KAFKA-9366:
------------------------------------
ALL // Sorry for being late. This KIP was originally passed for AK 3.0 but
dropped from the release for the lack of review. I think it will be included in
3.1.
If you need this feature urgently, please have a look at a custom build of
2.7.0 [here|http://home.apache.org/~dongjin/post/apache-kafka-log4j2-support/].
I could not complete it for 2.8.0 and 3.0 for my medical concerns but will
resume the work now.
If you are using log4j-appender, please have a look at
[KIP-719|https://cwiki.apache.org/confluence/display/KAFKA/KIP-719%3A+Add+Log4J2+Appender].
This KIP proposes a log4j2 equivalent for log4j-appender. I am also working on
a custom release of it.
Thank you again for your interest in my workings.
