             Summary: Tika external parsers cannot be turned off without patching the tika-app-XX.jar
                 Key: TIKA-1867
                 URL: https://issues.apache.org/jira/browse/TIKA-1867
             Project: Tika
          Issue Type: Bug
          Components: parser
    Affects Versions: 1.11
            Reporter: Roman Kratochvil


The CompositeExternalParser calls ExternalParsersFactory.create() which always uses configuration from org/apache/tika/parser/external/tika-external-parsers.xml. The issue is that this introduces performance regression as the parser initialization checks for presence of external commands (ffmpeg, exiftool) and that takes time.
Unfortunately, there is no way how to turn off this functionality without patching the tika-app JAR -- one has to either change the tika-external-parsers.xml or remove the whole CompositeExternalParser from list of services in /META-INF/services/org.apache.tika.parser.Parser.
