             Summary: impala-shell displays DeprecationWarning when using Python >=3.10
                 Key: IMPALA-12219
                 URL: https://issues.apache.org/jira/browse/IMPALA-12219
             Project: IMPALA
          Issue Type: Bug
          Components: Clients
    Affects Versions: Impala 4.3.0
            Reporter: Joe McDonnell


Ubuntu 22 uses Python 3.10, which deprecated ssl.PROTOCOL_TLS. When impala-shell starts up, it produces this message:
{noformat}
Starting Impala Shell with no authentication using Python 3.10.6
SSL is enabled. Impala server certificates will NOT be verified (set --ca_cert to change)
Warning: live_progress only applies to interactive shell sessions, and is being skipped for now.
/home/impdev/Impala/shell/build/impala-shell-4.3.0-SNAPSHOT/ext-py3/thrift-0.16.0-py3.10-linux-x86_64.egg/thrift/transport/TSSLSocket.py:53: DeprecationWarning: ssl.PROTOCOL_TLS is deprecated{noformat}
This doesn't seem to be coming from impala-shell code, so we will need to track down what is using this.

This is somewhat harmless, except that it causes test failures for custom_cluster/test_client_ssl.py, which asserts that DeprecationWarning is not in the output.

    shell_options = ["--ssl", "-q", "select 1 + 2"]
    result = run_impala_shell_cmd(vector, shell_options, wait_until_connected=False)
    for msg in [self.SSL_ENABLED, self.CONNECTED, self.FETCHED]:
      assert msg in result.stderr
    assert self.DEPRECATION_WARNING not in result.stderr <-----{noformat}
