> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Matt Gilman
> Fix For: 0.0.1
>
>
> This requires that when we swap FlowFiles Out that we always sync to ensure
> that we won't have EOF if we've finished writing!!
> Also, in order to ensure that we don't increment the queue count on restart
> when the file is incomplete, we need to write out to a temporary "xxxx.part"
> file and then rename to xxxx after calling FileDescriptor.sync()
