I have installed cassandra following this link https://linuxize.com/post/how-to-install-apache-cassandra-on-centos-7/. But when I start the cassandra service after installation, it shows this error:
Job for cassandra.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status cassandra.service" and "journalctl -xe" for details.
systemctl status cassandra has the following output:
