Description

Ubuntu 22 uses Python 3.10, which deprecated ssl.PROTOCOL_TLS. When impala-shell starts up, it produces this message:

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

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.

    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 <-----
