[jira] [Commented] (TIKA-1867) Tika external parsers cannot be turned off without patching the tika-app-XX.jar

["Nick Burch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-1867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15159042#comment-15159042 ] 

Nick Burch commented on TIKA-1867:
----------------------------------

You should be able to exclude the CompositeExternalParser with a ~5 line Tika Config file, which requires no patching or jars. Just use default parser but with a parser exclude for that one parser

See http://tika.apache.org/1.12/configuring.html for more on how to configure Tika, including an example of how to disable just one parser in config

> 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.
