------------------------------------------------------------
I tested with the latest build - solr-6.4.0-222,reloading collection/cores with
AnalyzingInfixSuggester still failed with LockObtainFailedException.
It failed with same error even after after solr.
It can be easily reproduced, add a suggest component, then ***build the
suggester***: suggest?suggest.build=true. Then reload collection or cores.
- Seems the key to reproduce the issue is we need build the 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?
