Re: Potential Problems on Discarding Return Values

Hi Adam,

The mailing list strips a lot of attachments, your PDF included. The best way I 
have found to share this kind of information with the community is to put it on 
the Apache NiFi Wiki [1] or post a GitHub Gist [2], etc. Thanks.

Hi,

Sorry, I did not realize, that this confluence page might not be 
available for some devs.

Hi,

Upon checking some behaviours in NiFi with Tamas Palfy, we have found 
that function signatures like this can be a frequent source of error:


|public FlowFile penalize(FlowFile flowFile) { ... }|

I documented the issue here:

https://cloudera.atlassian.net/wiki/spaces/ENG/pages/610534373/Discarding+Return+Values+in+NiFi

It would be nice if a Java dev with some spare time could look more 
into the issue and share their findings.


Cheers,
Adam
