----------------------------------
Summary: Allow environment variable to set output directory of
Kafka Connect logs
Key: KAFKA-9833
URL: https://issues.apache.org/jira/browse/KAFKA-9833
Project: Kafka
Issue Type: Improvement
Components: KafkaConnect
Reporter: Brandon Moe
Currently in Kafka Connect I believe that if you want to change what file logs
are written to you need to include a new log4j .properties file and then
override the *KAFKA_LOG4J_OPTS* environment variable. This can be [witnessed
here|[https://github.com/apache/kafka/blob/trunk/bin/connect-distributed.sh]].
I believe there is a valid use case for allowing a separate environment
variable such as *CONNECT_LOG4J_DIR* or similar to allow a user simply to chose
where the logs are written. This makes sense to me in a case where the default
.properties file works great but we simply want to change the output location.
An example could be if we are deploying to Kubernetes or similar and want to
write logs to a persistent volume. With an environment variable dedicated to
this use it saves busy work and extra steps while providing the desired
functionality succinctly. In the case when the variable is not set we simply
revert to the default settings. I do not believe I am alone on wanting this use
case as I have come across several other Stack Overflow and similar posts.
I believe this change would be pretty simple to implement and I would like to
take a shot at it if this seems legitimate, would love some feedback
Best,
Brandon
