Increase OCR timeout

[opensemanticsearch]

Tika default OCR timeout of 120 not enough if multiple parallel processed documents or images doing OCR which leads to Tika OCR timeouts and so Tika exception for full document(s)

[Mandalka]

The build script of the Debian Package now extracts the OCR config org/apache/tika/parser/ocr/TesseractOCRConfig.properties from the Tika Server JAR, changes timeout setting and adds/overwrites with changed config to/in the Tika Server JAR of the package.

If anybody needs to modify the timeout via REST, just add a header with "X-Tika-OCRTimeout: 200" for 200 seconds of timeout.

Example:

curl -T file_to_ocr.jpg localhost:9998/tika --header "X-Tika-OCRTimeout: 200"

Thanks for your tip, will add that in ETL plugin for the case someone uses a Tika on another server/installation which is not our preconfigured Tika deb package.

Timeout settings now by Open Semantic ETL using header X-Tika-OCRTimeout for Tika-Server.
