>
> 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.
