Michael McCandless commented on LUCENE-425:
-------------------------------------------
I believe the root cause of this issue was resolved with LUCENE-701: we no
longer rename files when writing a Lucene index.
Are you able to get this issue to happen with Lucene 2.2?
> "Cannot rename segments.new to segments"
> ----------------------------------------
>
> Key: LUCENE-425
> URL: https://issues.apache.org/jira/browse/LUCENE-425
> Project: Lucene - Java
> Issue Type: Bug
> Components: Index
> Affects Versions: 1.4
> Environment: Operating System: Windows XP
> Platform: PC
> Reporter: Mikko Noromaa
>
> AddDocument periodically fails with "Cannot rename segments.new to segments".
> Sometimes it happens after 10,000 documents, sometimes after 200,000
> documents.
> My index is placed on a FAT partition. My Lucene version is 1.4.3. I am using
> a single IndexWriter object and doing all AddDocuments calls serially from a
> single thread.
> I saw some discussion about this problem in the mailing lists, but looks like
> the problem wasn't completely eliminated yet.
> My suggested solutions are as follows:
> - If renameTo() fails, wait some time and retry. After this, apply the other
> methods that are now in FSDirectory.java. Retry them as well after waiting
> for
> some time.
> - In the IndexWriter constructor, check for 'segments.new' if 'segments'
> cannot be found. This would allow recovery if FSDirectory failed on a
> previous
> run. Now I have to write the recovery code myself outside of Lucene.
