---------------------------------
Summary: System tests attempting to start processors while still
validating
Key: NIFI-10290
URL: https://issues.apache.org/jira/browse/NIFI-10290
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
We periodically see system tests fail because they attempt to start a processor
while the Processor is still Validating. Most of the time, this is obvious by
looking at the logs, which indicate that the Processor cannot be started
because it is Validating.
Less obvious, though, we sometimes see tests fail because they trigger a
Process Group to start processing. This will start all processors that are
valid. However, if a processor is still validating, it will be simply skipped
over without error. This can cause failures that are much harder to understand.
We should update the NiFiClientUtil used by system tests. The startProcessor()
method should wait until the processor is no longer validating before
attempting to start it. Additionally, the startProcessGroupContents() method
should wait until all processors within the group have finished validating
before making the start request.
We should then update the system tests to make use of these methods everywhere
instead of using the ProcessorClient.startProcessor method.
