Subject [jira] Updated: (NUTCH-610) Can't Update or modify an index while web gui is running
Date Mon, 11 Feb 2008 18:20:09 GMT


Ciminera Frederic updated NUTCH-610:

    Attachment: NutchBeanNoLock.patch

This early patch contains an implementation of a NutchBean that creates a new Searcher for
each query and release it once finished to avoid keeping a lock on the index files.

This patch is not yet compatible with distributed search servers

> When the search web application is started a NutchBean is created and initializes its
searcher on the index files (and also a FetchedSegment on segments).
> This index searcher (and also FetchedSegment) is holding a lock on the files on disk
that prevent the index to be updated or modified.
> It would be nice to be able to update an index without having to restart the web server.
