> If a Processor provides a {{FlowFileFilter}} to the
> {{ProcessSession.get(FlowFileFilter)}} method, and the {{FlowFileFilter}}
> throws an exception, the FlowFile that the filter is evaluating, and all
> other FlowFiles that it has evaluated, become inaccessible. The queue still
> shows the data available but the Processor can't get to the FlowFiles. Upon
> restart of NiFi, the FlowFiles are properly restored and accessible.
