Actually it does have to be public, it is referenced from multiple packages.
> Add support for ORC format
> --------------------------
>
> Key: NIFI-1663
> URL: https://issues.apache.org/jira/browse/NIFI-1663
> Project: Apache NiFi
> Issue Type: New Feature
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Fix For: 1.0.0
>
>
> From the Hive/ORC wiki
> (https://cwiki.apache.org/confluence/display/Hive/LanguageManual+ORC):
> The Optimized Row Columnar (ORC) file format provides a highly efficient way
> to store Hive data ... Using ORC files improves performance when Hive is
> reading, writing, and processing data.
> As users are interested in NiFi integrations with Hive (NIFI-981, NIFI-1193,
> etc.), NiFi should be able to support ORC file format to enable users to
> efficiently store flow files for use by Hive.
