Subject Re: [jira] Commented: (LUCENE-665) temporary file access denied on Windows

Correct, but if you are using a distributing index, you should make  
copies of it, not access the same index (on one machine) from  
multiple machines. If doing this, you would still need some sort of  
server process on the master, and if that is available, it can  
control the distribution of the index - so once again, no problem  
with NFS do to renames, etc.

I guess I just don't see how any NFS issues should matter in a  
properly deployed Lucene - even multiserver - environment.

It is similar to the class reason why unix databases never used/ 
needed file locks - the server process managed the locks internally -  
which is far more efficient.
