> If the "Directory" or "File Filter" property is changed in ListHDFS, and then the Processor is started, a change in the Primary Node can result in resetting the Processor state.
> To replicate, create a ListHDFS Processor in a cluster. Configure to point to some directory and start the processor running on Primary Node. After the listing has completed, disconnect the Primary Node from the cluster to trigger the Primary Node to change. At this point, the Processor will reset its state and re-list everything.
> Note that once NiFi has been restarted, this behavior will no longer exist until the Processor's Directory or "File Filter" property is changed again. It also will not happen again if the new Primary Node has already reset the state as a result of the property change.
