I like it -- I'll start working on it.
> UnpackContent cannot unpack any type of flowfile
> ------------------------------------------------
>
> Key: NIFI-2611
> URL: https://issues.apache.org/jira/browse/NIFI-2611
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 0.7.0
> Reporter: Joseph Gresock
> Assignee: Joseph Gresock
>
> Two possibly separate problems:
> *Flowfile-stream-v2 and v3*
> This may be a problem with either MergeContent's production of
> flowfile-stream v2 and v3, or with UnpackContent's inability to unpack them,
> not sure which. Here is a screen shot with how to reproduce it:
> https://ibin.co/2sCwqbFbAs3a.png
> Essentially, when you pack a flow file as flowfile-stream v2 or v3, a
> subsequent UnpackContent set to the respective type fails with the error
> "Cannot unpack {} because it does not appear to have any entries".
> *Flowfile-tar-v1*
> When selecting flowfile-tar-v1 from UnpackContent, you immediately get
> @OnScheduled error failure as soon as you start the processor, which prevents
> it from processing any incoming flow files. Here is a screenshot:
