Prevent Lucene from creating index directory automatically










0















I've been reading the one-time-created-index with:



 IndexReader reader = DirectoryReader.open(index);


where index is



 Directory index = FSDirectory.open(Paths.get("src" + File.separator + "main" + File.separator + "resources" + File.separator + "luceneIndex"));


FSDirectory.open() attempts to create directories, but the production environment is read only.
Is it possible to get the index Directory in read only mode?

          The reason that your code is failing is because by default FSLockFactory is used to obtain the lock on the index to prevent corruption. To obtain the lock it creates lock file. Obviously, in your case it's not possible, so you need to use another implementation - NoLockFactory.



          Directory index = FSDirectory.open(Paths.get("/tmp/test"), NoLockFactory.INSTANCE);
