While we're still using Cassandra, it might be useful to add the details of this list post as a FAQ entry when people have a failing Cassandra that cannot recover (i.e. Cassandra won't start or quit quickly after start).

The instructions are:

systemctl stop cassandra
systemctl stop httpd
pkill -9 -f java
cd /var/lib/cassandra/data/system/local/

Move the last Cassandra DB file, something like system-local-jb-xyz-Data.db to a temporary directory (just in case). Then

systemctl start cassandra
systemctl start httpd

Or

init 0
init 6

This method will result in some data loss. Do we still recommend this with an appropriate warning?
