Tika error "Media type alias already exists"
--------------------------------------------
Key: NUTCH-618
URL: https://issues.apache.org/jira/browse/NUTCH-618
Project: Nutch
Issue Type: Bug
Components: mime_type_detector
Affects Versions: 1.0.0
Reporter: Andrzej Bialecki
After the upgrade to the latest Tika jar we see a lot of errors like this:
2008-03-06 08:07:20,659 WARN org.apache.tika.mime.MimeTypesReader: Invalid
media type alias: text/xml
org.apache.tika.mime.MimeTypeException: Media type alias already exists:

This is caused most likely by the duplicate tika-mimetypes.xml file - one copy
is embedded inside the Tika jar, the other is found in Nutch conf/ directory.
The one inside the jar seems to be more recent, so I propose to simply remove
the one we have in conf.
