Summary: Flaky System Test
FlowSynchronizationIT.testUnnecessaryProcessorsAndConnectionsRemoved
Key: NIFI-15655
URL: https://issues.apache.org/jira/browse/NIFI-15655
Project: Apache NiFi
Issue Type: Improvement
Reporter: Pierre Villard
Assignee: Pierre Villard
I have seen some occurrences of the below failure when building locally. After
investigating the troubleshooting logs of the system tests, it seems to be
around transient errors around heartbeating when using zookeeper.
{code:java}

{code}
This may be also the reason for some flakiness on additional system tests.
