-----------------------------------------
Summary: python dtest fails to talk to 2.2 using protocol 4 but
cqlsh has no issue
Key: CASSANDRA-16354
URL: https://issues.apache.org/jira/browse/CASSANDRA-16354
Project: Cassandra
Issue Type: Bug
Components: CI, Test/dtest/python
Reporter: David Capwell
https://app.circleci.com/pipelines/github/dcapwell/cassandra/850/workflows/79486fdd-06d0-4d04-aa32-0fa648182356/jobs/5019/artifacts
We see that upgrade tests which talk to 2.2 clusters fail with the following
error
{code}
> ???
E cassandra.cluster.NoHostAvailable: ('Unable to connect to any servers',
{'127.0.0.1:9042': DriverException('ProtocolError returned from server while
using explicitly set client protocol_version 4',)})
{code}
For some reason, setting protocol version 4 causes 2.2 to fail, but this does
not happen when using cqlsh (from trunk)
{code}
./bin/cqlsh --protocol-version=4
Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 2.2.20-SNAPSHOT | CQL spec 3.3.1 | Native protocol v4]
Use HELP for help.
