There are a lot of strings for Cassandra amongst your command suggesting that this might well be a database server of some kind. We have no clue what you might be using it for to be able to suggest an alternative. You might be able to remove cassandra using sudo apt-get remove cassandra and see what breaks but only you can say whether that might be a problem.
