Where is the error log file destination for Zookeeper distributed with Kafka?

Question

I'm a bit confused on how to configure where the error log files are written for Zookeeper when running ZK and Kafka on the same node. I understand it uses log4j and there is a zookeeper.properties file. I assume it is using some sort of default out of the box. If I do:

sudo lsof -p 31311 | grep log | grep zoo

I get:

java    31311 root    1w      REG              259,1     24962  134739 /home/ec2-user/zookeeper-start-log
java    31311 root    2w      REG              259,1     24962  134739 /home/ec2-user/zookeeper-start-log
java    31311 root    3w      REG              259,1     22350 1050171 /opt/Kafka/kafka_2.11-1.1.0/logs/zookeeper-gc.log.0.current
java    31311 root   94w      REG              259,1  67108880  394260 /var/local/zookeeper/data/version-2/log.1

If I want to explicitly specify my error log locations for zookeeper, what exactly do I specify in the zookeeper.properties file?

Answer 1

If you're using the provided zookeeper-server-start script, then Kafka and Zookeeper share the same log4j.properties file.

In there, you can reconfigure the DailyRollingFileAppender or ConsoleAppender based on the package names for Zookeeper clients and/or Kafka

If you want to reconfigure the data stored by Zookeeper other than the service logs, the Zookeeper documentation should cover those as well as the defaults
