-------------------------
Summary: Inconsistancy in queue state. Can not empty a queue.
Key: NIFI-3475
URL: https://issues.apache.org/jira/browse/NIFI-3475
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.1.0
Reporter: n h
During development a custom processor (that use FlowFileFilter to get flowfiles
in) we meet some inconsistancy in queues.
I connect a GenerateFlowFile to custom-processor and start both. Then I stoped
both. The connection shows a few flowfiles in the queue (due to filtering) but
I could not delete them until I gracefully restart the Nifi server. I reroute
the connection to a funnel and then that funnel to another funnel to build a
pipe. flowfiles in the queue were not transfered to 2nd connection. Also they
do not expire. There must be some inconsistancy in queue functionality or
presentation that shows non-empty queue state but flowfiles nor could be
deleted neighther expire or transferred.
(If it helps, there is a bug in OnTrigger code of my processor that produce
NullPointerException during the test but my question is not about this bug).
