Michael McCandless commented on LUCENE-1877: -------------------------------------------- I think we should also fix NativeLockFactory so that if the write lock is in the index dir it doesn't generate the large digest in the file name. That digest is problematic when two different machines access the same physical dir via different mount names, since that results in different lock file names. > Improve IndexWriter javadoc on locking > -------------------------------------- > > Key: LUCENE-1877 > URL: https://issues.apache.org/jira/browse/LUCENE-1877 > Project: Lucene - Java > Issue Type: Improvement > Components: Javadocs > Reporter: Mark Miller > Priority: Trivial > Fix For: 2.9 > > Attachments: 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).
