Logkafka - Collect logs and send lines to Apache Kafka 0.8+ Introduction 中文文档. Logkafka sends log file contents to kafka 0.8 line by line. It treats one line of file as one kafka message. See FAQ if you wanna deploy it in production environment. Log collecting configuration management with zookeeper. Note: To know the forepath directory, use 'pwd' command. It will display its name. Step3: After setting the path, apply 'kafka-' or 'kafka-topics.sh' command to know whether the path is successfully set. If the mac users have Brew installed, they can use it for Kafka installation. There are following steps used to install Apache Kafka using brew. Installation and environment setup for Kafka on mac os. To install Apache Kafka on Mac or any system, the prerequisite is the only Java(Java 8 ). First, we will look into the installation steps of Java and then we will proceed to set up Apache Kafka.

Why not Kafka 0.11 or 1.0

• homebrew kafka version using 0.11 and could not launch on my computer, and it is hard to know detail why homebrew/kafka failed. (issue)
• Transactional Coordinator still not support by sarama golang client (golang) (issue)

Install Kafka 0.8 manually in 2017/11

How to verify your installation?

(in your kafka path)

Verify it

Or your can use golang client to verify it:

Troubleshooting

• Check if any port already occupy by some app. refer: (Who is listening on a given TCP port on Mac OS X?)
• After your uninstall zookeeper, the zookeeper service will not be removed. Please remember to remove it manually.
