i know removing keyspaces in /var/lib/cassandra/data/ exception isn't thrown anymore , cassandra starts up. there has cleaner solution.

most of time happens when start cassandra special underprivileged user named illustration cassandra. lastly time started cassandra root.

now have files/folders owned root , can't accessed cassandra user.

to solve problem need run root (if cassandra underprivileged user): chown -r cassandra:cassandra /var/lib/cassandra/data/*

after doing cassandra should start normally.

java exception cassandra
