Lance Norskog updated SOLR-2186:
--------------------------------
Attachment: TikaResolver.patch
This patch file fixes up the DataImportHandler so that the TikaEntityProcessor
works under threads.
The technique is to pass in a resolver when creating a ThreadedContext
(wrapper). This allows TikaEP.firstInit() to work. However, TikaEP.nextRow is
called with a context without a functioning resolver, so: TikeEP caches the
resolver given in firstInit() and uses it during nextRow() instead of using the
one it should use.
This is not intended as fix patch; it merely demonstrates the problem.
The patch is made with 'git diff' and I still haven't mastered it; some 'patch'
programs may not like it.
