How to start: /opt/homebrew/opt/cassandra/bin/cassandra -f

Solution:

1. Find where is jna-..*.jar located. you can do this using find . -name '*.jar' | grep cassandra
2. Browse to https://search.maven.org/artifact/net.java.dev.jna/jna/5.8.0/jar and download the jar from top-right downloads button on the page.
3. Replace your jna-..*.jar file with the one you downloaded. In my case in replaced jna-5.6.0.jar. Remember to keep the file name as your previous file name. Example I moved jna-5.8.0.jar and renamed as jna-5.6.0.jar

mv /Users/mansooralikhan/Downloads/jna-5.8.0.jar /opt/homebrew/Cellar/cassandra/4.0.1/libexec/jna-5.6.0.jar

4. Restart cassandra

To echo Mansoor's answer, I'll add that the version of JNA shipped with Apache Cassandra 4.0 unfortunately is not compatible with the M1 architecture.

To remedy this, head to the "downloads" section of the JNA GitHub repo, where you should find the latest version of the JNA jar file.

https://github.com/java-native-access/jna#jna

Download JNA version 5.8 or higher, and replace the existing jna-5.6.0.jar file in Cassandra's lib/ directory (tarball-based installs).
