Hi, this should be fixed in coming Lucene 5.3: https://issues.apache.org/jira/browse/LUCENE-6542
The reason for this behavior is that we need to ensure that the directory exists before we open it. For that it calls Files.createDirectories - which requires write access. The fix only calls createDirectories if the index does not exist.
