The thing you are asking for is Rolling Restart a cassandra cluster. There are so many reason to restart a cassandra cluster. I'm just mentioning some below-

  1. when you update any value in cassandra.yaml. (As you mentioned above)
  2. When your nodetool got stucked somehow. such as- you gave command nodetool repair and cancelled the command but it got stucked behind, then you won't be able to give another nodetool repair command.
  3. When you are adding a new node to cluster and you got stream_failed due to nproc limit. That time your running cluster nodes could be down to this issue and going to hold the status.
  4. When you don't want to use sstableloader and you need to restore your data from snapshots. That time you need to provide your snapshots to the data_directory on each node and rolling restart.
  5. When you are about to upgrade your cassandra_version.
