Andrzej Bialecki commented on NUTCH-662:
-----------------------------------------
+1 on moving to 2.4 anyway. Regarding the patch: I think this is a viable
solution for now. Performance-wise the impact of local buffering, especially in
case of large indexes, could be significant - the indexing may take much longer
with this change.
Anyway, this problem should be reported to the Lucene devs, so that they may
discuss what's the best strategy to address this in the future.

> Upgrade nutch to use Lucene 2.4. This release changes the lucene file
> format. New indexes created by this lucene version will NOT be readable by
> older versions. Lucene 2.4 can read and update older index formats although
> updating an older format will convert it to the new format. There are also
> some performance and functionality improvments.
