Steve Rowe updated LUCENE-7564: ------------------------------- Attachment: LUCENE-7564-fix-random-NRT-failures.patch After several thousand beasting iterations, I still haven't been able to reproduce the {{testRandomNRT()}} failures. I'm attaching a patch that I think will address the problem, which AFAICT is that under multi-threaded use, in {{lookup()}}, the suggester’s {{searcherMgr}} data member could be re-assigned in the middle of a searcher acquire/release cycle due to the changes introduced in LUCENE-7564 - as a result these could be imbalanced, with {{acquire()}} called on one instance and {{release()}} called on a different one. The patch takes a local {{SearcherManager}} reference and calls {{acquire()}}/{{release()}} though it in every place these are called in {{AnalyzingInfixSuggester}} (rather than calling through the {{searcherMgr}} data member). I'm beasting {{AnalyzingInfixSuggester}} with this patch, and I'll commit later today if there are no failures. > AnalyzingInfixSuggester should close its IndexWriter by default at the end of > build() > ------------------------------------------------------------------------------------- > > Key: LUCENE-7564 > URL: https://issues.apache.org/jira/browse/LUCENE-7564 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Steve Rowe > Assignee: Steve Rowe > Fix For: master (7.0), 6.4 > > Attachments: LUCENE-7564-fix-random-NRT-failures.patch, > LUCENE-7564.patch, LUCENE-7564.patch > > > From SOLR-6246, where AnalyzingInfixSuggester's write lock on its index is > causing trouble when reloading a Solr core: > [~gsingers] wrote: > bq.
