> Project: Apache Apex Malhar
> Issue Type: Bug
> Reporter: Thomas Weise
> Priority: Minor
>
> No inputs received, empty maps produced. The operator is probably only used
> in demos, and that's how the issue was noticed. Word count result files
> filled with just {}s. The suggested solution is to change the operator to
> only emit non-empty results.
