> We have a Apache Cassandra cluster with 36 nodes running on k8s, cqlsh client was installed in a separate namespace. cqlsh is downgrading version from v4 to v3 on some of the nodes but we have a case where all the nodes need to connect to v4, this is a requirement to set UNSET for avoiding null values to be converted to tombstones (only v4 is supported). 
> {code:java}
> cqlsh 10.1.2.3 --ssl --protocol-version=3
> Connected to production at 10.1.2.3:9042.
> [cqlsh 5.0.1 | Cassandra 3.11.5 | CQL spec 3.4.4 | Native protocol v3]
> Use HELP for help. 
> cqlsh>
> cqlsh 10.1.2.3 --ssl --protocol-version=4
> Connection error: ('Unable to connect to any servers', {'10.1.2.3': DriverException('ProtocolError returned from server while using explicitly set client protocol_version 4',)})  {code}
