Michael McCandless commented on LUCENE-1877: -------------------------------------------- OK. I would strongly recommend using the lock stress test (LockStressTest/LockVerifyServer) in Lucene to verify whichever locking you're trying is in fact working properly. > Use NativeFSLockFactory as default for new API (direct ctors & FSDir.open) > -------------------------------------------------------------------------- > > Key: LUCENE-1877 > URL: https://issues.apache.org/jira/browse/LUCENE-1877 > Project: Lucene - Java > Issue Type: Improvement > Components: general/javadocs > Reporter: Mark Miller > Assignee: Uwe Schindler > Fix For: 2.9 > > Attachments: LUCENE-1877.patch, LUCENE-1877.patch, LUCENE-1877.patch, > LUCENE-1877.patch > > > A user requested we add a note in IndexWriter alerting the availability of > NativeFSLockFactory (allowing you to avoid retaining locks on abnormal jvm > exit).
