lucene NFS support

Hi,

 

Does anyone know whether Lucene plans to support NFS in later
release(2.0)? We are planning to integrate Lucene into our products and
cluster support is definitely needed. We want to check whether NFS
support is in the plan or not before implementing a new file locking
ourselves with it.

 

Thanks.

Chunhe

I think that nio-based locking would probably fix this, and could easily 
be provided in addition or in place of the existing locking mechanism. 
I think the last time this was considered Lucene was still attempting to 
be compatible with Java 1.3.  But I think Lucene 2.0 is aimed at Java 1.4.

No that doesnt seem to be the problem.

Anyone have any other ideas?

I had a problem in the past with security on the folder where your index 
is located...but your error does not seem to show that ... I would check 
anyway though...

Hi all,

I wrote a lucene program which runs fine under Linux and Mac but fails on 
most Windows machines. (I have managed to get it to work on one version of 
XP however)

Specifically when i open or search the index i get the following error 
message.

Any help would be appreciated,
Cheers,
Chris

Re: lucene NFS support

Hi Chunhe,

There are no NFS-specific plans.  Out of personal curiosity - why go for NFS and not NAS?
