Impala ODBC driver connection fails with SSL error.
Note: we haven't enabled SSL for any of the service in the cluster.
But from the error message it looks like the service is using SSL. Are you sure that you are not using the ClouderaManager's Auto TLS feature? Verify it in the Impala Service configuration.
I dont see any error related to SSL in impala daemon logs,we haven't checked anything related to SSL in ODBC driver settings.
Note: He connected successfully a few days ago ,but all of a sudden this issue raised.
