My Nutch cycle completed successfully over the weekend. Deployment and
searching also works fine.
The only major/minor functional difference I noticed was that during fetching
Hadoop stored the fetched data in memory until it reached a certain amount (100
megabytes or so) then wrote it all to disk (in the Hadoop temp directory) at
once. During the write operation, which lasted no more then 8 seconds each time
the Java thread count would lower down to between 6 and 10. This differed from
previous versions where the data was streamed in real-time, but I don't see
this costing anything in performance as the Java processes didn't lock despite
the lowering of total threads.

Great, thanks a lot.
I have started a complete Nutch cycle (generate, fetch, updatedb, invertlinks,
index and dedup) on a 13 million document segment, and this should take no
longer then a couple days. I will let you know of any problems, but hopefully
it will work out with no errors at all.
All this testing will be based off revision 515791 in trunk.

To be precise, the version is 0.11.2 release and it's been committed
just now (rev. 515791). Your help in testing would be most welcome ...
