Ansible Playbook fails start Apache Cassandra

Question

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

● cassandra.service - LSB: distributed storage system for structured data
   Loaded: loaded (/etc/rc.d/init.d/cassandra; bad; vendor preset: disabled)

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
java.lang.ExceptionInInitializerError: null

    at org.apache.cassandra.db.commitlog.CommitLog.<clinit>(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

[Unit]
Description=Cassandra Cluster Node Daemon
[Service]
Type=forking
User=cassandra
ExecStartPre=/usr/bin/echo "Starting Cassandra Daemon"
ExecStart=/usr/sbin/cassandra
ExecStartPost=/usr/bin/echo "Cassandra Daemon Running"
ExecStopPost=/usr/bin/rm -rf /cassandra/saved_caches;/usr/bin/echo "Cassandra Daemon Stopped"
SuccessExitStatus=143
[Install]
WantedBy=default.target
