Ansible Playbook fails start Apache Cassandra I have been tried ran a Ansible Playboo, but after change the cassandra.yml when the service tries start I received this error bellow:

In my cassandra.yml I just change the mount point/path where Cassandra stores the data and sure that this works.
Looking at Cassandra system.log I found:
ERROR [main] 2021-04-05 16:57:34,074 CassandraDaemon.java:822 - Exception encountered during startup

    at org.apache.cassandra.db.commitlog.CommitLog.&lt;clinit&gt;(CommitLog.java:65)
    ... 3 common frames omitted

It's weird because I create the directory at new mount point with cassandra:cassandra permitions:
drwxr-xr-x  2 cassandra cassandra   6 abr  5 14:46 commitlog
drwxr-xr-x  2 cassandra cassandra   6 abr  5 14:46 data
drwxr-xr-x  2 cassandra cassandra   6 abr  5 16:53 hints
drwxr-xr-x  2 cassandra cassandra   6 abr  5 16:53 saved_caches

I have been spend long hours trying solve but without success, someone my can help me?
I found my fault.
It's necessary define a cassandra.service to Systemd manages Cassandra:
path: /etc/systemd/system/cassandra.service
And adjust like you installation
