Hi Dojo
Currently we are facing an issue in our prod Cassandra running in Linux server which is then connecting with Prod Dataminer system. Actually we were migrating from oracle java to Open jdk 11 in Cassandra server. While doing this the installation of jdk 11 happened successfully. But when we tried to remove the old oracle java (jre 1.8), the Cassandra service also got removed from the server. Due to this Dataminer lost connection with Cassandra node. We found that the removal of the oracle java also removed Cassandra related directories as well. As of now we don't have any clue why the Cassandra service is removed with oracle java (jre 1.8).
Thanks

Hi Mohan,
Without seeing exact commands that you executed to uninstall Java, I'm afraid it won't be possible to answer why it resulted in complete uninstallation of Cassandra. A lot depends on your environment: the specific Linux distribution and the specific method used to install Java and Cassandra.
I quickly checked public documentation on Cassandra and haven't found any similar reported issues. Therefore, this must be a very specific scenario that occurred in your environment and not a widely known issue.
