After installing Cassandra 3.11 version on ubuntu 19.04 I am getting the following error once I fire command cqlsh

root@dnilesh:/etc/cassandra# cqlsh
Connection error: ('Unable to connect to any servers', {'127.0.0.1': ProtocolError('Unexpected response during Connection setup: AttributeError("\'module\' object has no attribute \'decompress\'",)',)})

Cassandra service is up and running but not able to connect cqlsh terminal.

For me this worked:

$ export CQLSH_NO_BUNDLED=true
$ cqlsh

After the last cqlsh there was a problem with missing cassandra-driver, and installing through sudo pip... didn't work I had to switch to root user!

$ sudo su
# pip install cassandra-driver
# cqlsh

you can try with cqlsh [ip address] (replace the brackets with the IP address of the host) or cqlsh $(hostname) (no substitutions are needed)
