Subject [jira] Updated: (NUTCH-618) Tika error "Media type alias already exists"
Date Mon, 02 Jun 2008 04:21:45 GMT

     [ https://issues.apache.org/jira/browse/NUTCH-618?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris A. Mattmann updated NUTCH-618:
------------------------------------

    Attachment: NUTCH-618.Mattmann.patch.060108.2.txt

Updated patch that includes the updates to tika-mimetypes.xml identified by Dennis Kubes.
Thanks, Dennis!

Dennis tested this on his testbed environment and it ran through great. So, I'd like to call
for 24-48 hr review on the patch, and then if no objections, I'd like to commit it.

Thanks!

Cheers,
 Chris

> After the upgrade to the latest Tika jar we see a lot of errors like this:

alias: text/xml

> 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.
