I was in the middle of the process of fixing NUTCH-193 (moving things to
the new Hadoop project) when you made this commit. I merged in those
changes you made to things still in Nutch, but those things moved to
Hadoop still have the unused imports you removed. Sorry! I also
perhaps introduced a few unused new imports in the process of fixing
NUTCH-193. If you have a tool that makes removing these simple, please
feel free to run it again.
