Matt Burgess created NIFI-4490:
----------------------------------
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
