Description

If an indexing cycle fails for some reason it may leave orphan files in local directory. Later on in next indexing cycle Lucene would try to create files with same name on local disk and this may fail on Windows where such files may have been memory mapped and hence cannot be deleted.

We should analyze such a scenario and see if system can handle the failure case properly
