Currently I have a data center with 3 nodes. After I make changes to cassandra.yaml file, I run the following commands on each node to restart.
nodetool drain sudo service dse stop sudo service dse start
This throws an error. Which can be resolved by deleting the commit-logs, saved-caches and data from /var/lib/cassandra.
But I do not want to delete these files. Why am I not able to restart DSE without having to remove these files? I am losing all my data in this process.
Would really appreciate if someone could head me in the right direction with respect to restarting DSE.
