> MergeRecord can NPE if all flow files have 0 records
> ----------------------------------------------------
>
> Key: NIFI-6041
> URL: https://issues.apache.org/jira/browse/NIFI-6041
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.9.0
> Reporter: Bryan Bende
> Priority: Minor
>
> If you create a MergeRecord processor with a Max Bin Age set, and then send
> in a bunch of flow files that all have no records, then eventually it will
> attempt to complete a bin based on the bin age, but will NPE because the
> record writer was never initialized...
