--------------------------------
Summary: Node can fail to offload due to
ConcurrentModificationException
Key: NIFI-9365
URL: https://issues.apache.org/jira/browse/NIFI-9365
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
I created a System Test that create a cluster, add some processors to the flow,
and run the flow. Then disconnect one of the nodes and offload it. When
successful, reconnect node, destroy flow, and start over. Repeat for several
iterations.
Intention here was to ensure that we successfully complete offloading after
trying many times. After several iterations, I encountered a
ConcurrentModificationException in StandardProcessorNode#getActiveThreads. This
caused the node not to complete its offloading.
