Question

I get the following message when executing cqlsh.bat on the command line

Connection error: (\'Unable to connect to any servers\', {\'127.0.0.1\': ProtocolError(\         


        

Answer 1

ProtocolError("cql_version '3.3.0' is not supported by remote (w/ native protocol). Supported versions: [u'3.2.0']"

Indicates that there is a version mismatch between the C* version you are running and the python driver run by CQLSH. Make sure they are all out of the same release.
