----------------------------------

             Summary: Repetitive events detected on changing the incorrect driver name in CaptureChangeMySQL
                 Key: NIFI-4490
                 URL: https://issues.apache.org/jira/browse/NIFI-4490
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Matt Burgess


Followed the below steps
1. In CaptureChangeMySQL, set the driver name to "com.mysql.some.driver"
2. Create a table in the test database and start the CaptureChangeMySQL processor
3. "Error creating binlog enrichment JDBC connection" error message is thrown which is correct.
This completes the first test. Next do the following
1. Correct the driver name
2. Reset the binlog events by running "RESET MASTER"
3. Clear the state of the CaptureChangeMySQL processor.
4. Start the CaptureChangeMySQL processor.
Result : The Create statement which was triggered when the driver was invalid is detected thrice in the tests that I carried out by CaptureChangeMySQL processor
Expected : The event should not have been detected at all since the binlogs have been deleted, state reset and the database pattern hardcoded to a single db
