jefferyyuan commented on SOLR-6246:
-----------------------------------
I am running on Solr 6.4 - solr-6.4.0-195.
But the problem still exists. Even restarting solr doesn't work - after restart
solr and reload collection or current node still fails with
LockObtainFailedException.
I even tried to manually delete the write.lock, then call
reload-collection/cores , it still failed again with same error.

> Core fails to reload when AnalyzingInfixSuggester is used as a Suggester

> Key: SOLR-6246
> URL: https://issues.apache.org/jira/browse/SOLR-6246
> Project: Solr
> Issue Type: Sub-task
> Components: SearchComponents - other
> Affects Versions: 4.8, 4.8.1, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4
> Reporter: Varun Thacker

>
> 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?
