--------------------------------
Summary: TailFile does not recover cluster-wide state when Primary
Node changes
Key: NIFI-4602
URL: https://issues.apache.org/jira/browse/NIFI-4602
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Reporter: Mark Payne
Assignee: Mark Payne
I created a TailFile processor and set the "File Location" property to
"Remote." I then added some text to a file and started the TailFile processor
(Primary Node Only).
I disconnected the primary node from the cluster. A second node became the new
Primary Node and continued tailing the data as expected. As new data was added,
the node continued to emit FlowFiles.
Then, I added Node 1 back to the cluster. Verified that Node 2 continued to
poll data. I then disconnected Node 2 so that Node 1 once again became the
Primary Node. At this point, Node 1 continued tailing from where it last left
off, not where Node 2 left off.
