[jira] [Updated] (SOLR-6246) Core fails to reload when AnalyzingInfixSuggester is used as a Suggester

["Varun Thacker (JIRA)" <ji...@apache.org>]

Varun Thacker updated SOLR-6246:
--------------------------------

    Attachment: SOLR-6246.patch

I experimented by adding a closeHook which gets called before the new SolrCore gets created. At least the core now reloads correctly.

This approach has one major disadvantage - There will be a short period where the suggester won't work since we close it before the new core has been registered.

Any ideas as to how should we tackle this in a correct way?

> LUCENE-5477 - added near-real-time suggest building to AnalyzingInfixSuggester. One of the changes that went in was a writer is persisted now to support real time updates via the add() and update() methods.
> When we call Solr's reload command, a new instance of AnalyzingInfixSuggester is created. When trying to create a new writer on the same Directory a lock cannot be obtained and Solr fails to reload the core.
> Also when AnalyzingInfixLookupFactory throws a RuntimeException we should pass along the original message.
> I am not sure what should be the approach to fix it. Should we have a reloadHook where we close the writer?
