[jira] Updated: (SOLR-2186) DataImportHandler multi-threaded option
throws exception
[ https://issues.apache.org/jira/browse/SOLR-2186?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
