Cassandra cqlsh - connection refused

Question

I\'ve just started working with Cassandra (datastax), version 2.1.3 and cqlsh version 5.0.1.

Cassandra starts up fine and the cluster is operational instantly.

Answer 1

Had same problem recently after downgrade from Cassandra 3.0 to Cassandra 2.2 on ArchLinux.

Unlike above solutions my problem wasn't in .cassandra, but version 3.0 left its configuration in /var/lib/cassandra directory.

Following commands solved my problem:

sudo rm -R /var/lib/cassandra
sudo rm -R /var/log/cassandra
sudo rm -R /usr/share/cassandra

Then i installed cassandra and everything worked again :)
