I installed Kafka and Zookeeper on my OSX machine using Homebrew, and I'm trying to launch Zookeeper and Kafka-server following this blog post.

zookeeper-server-start /usr/local/etc/kafka/zookeeper.properties works fine, as confirmed using telnet localhost 2181. Launching kafka-server-start /usr/local/etc/kafka/server.properties results in the following output (error at the end). What should I do to launch the Kafka server effectively?

$ kafka-server-start /usr/local/etc/kafka/server.properties

This is the issue:

org.apache.kafka.common.KafkaException: Failed to acquire lock on file .lock in /usr/local/var/lib/kafka-logs. A Kafka instance in another process or thread is using this directory.

There's another instance of kafka running. Kill it first.

You should be able to identify it with

lsof /usr/local/var/lib/kafka-logs/.lock

EDIT:

try brew services stop kafka first.
