True, and I did the same ('brew install tesseract') and got this

> Tesseract OCR Processor
> -----------------------
>
> Key: NIFI-1815
> URL: https://issues.apache.org/jira/browse/NIFI-1815
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Jeremy Dyer
> Assignee: Jeremy Dyer
> Attachments: 0006-changes-to-the-OCR-processor.patch,
> nifi_1815_1.x_patch.zip
>
>
> This ticket is a follow-up to NIFI-1718 minus the use of the Tika library
> Expose OCR capabilities through a new processor which uses the Tesseract
> library. Use of this processor would require that Tesseract be installed on
> the NiFi host. Since the processor will have a system dependency care must be
> taken to ensure that the overall NiFi cluster continues to function properly
> in the absence of the Tesseract system dependency even though the OCR
> processor itself will be unable to perform its duties. In the event that the
> system dependencies are not detected the processor should display a
> validation warning rather than failing or preventing the NiFi instance from
> booting properly.
> Properties expose to configure Tesseract
> tesseractPath - Path to tesseract installation folder, if not on system path.
> language - Language ID (e.g. "eng"); language dictionary to be used.
> pageSegMode - Tesseract page segmentation mode, defaults to 1.
> minFileSizeToOcr - Minimum file size to submit file to OCR, defaults to 0.
> maxFileSizeToOcr - Maximum file size to submit file to OCR, defaults to
> Integer.MAX_VALUE.
> timeout - Maximum time (in seconds) to wait for the OCR process termination;
> defaults to 120.
