Apache Ignite with log4J2 KafkaAppender - class not found
I'm trying to setup a Apache Ignite/GridGain node with a Log4J2 GridLogger.
Where The log4j config is calling a KafkaAppender to send the logs directly
to a kafka topic.
However the setup fails, when starting the node the required classes are not
found. I installed the kafka-clients-0.9.0.1.jar but still same error.

Just found out that Apache Ignite is using log4j2 version 2.3, while the
actual version for log4J2 is 2.8.
In the version 2.3 there is no support for KafkaAppender. I can reproduce
the issue in a separate Java program.

Is that log4j (1) Kafka Appender compatible with log4j2 ? To my
understanding there are completely differently developed. I could be wrong.

Hi,
I suppose you need kafka log4j appender [1] in classpath.
