Lewis John McGibbney commented on NUTCH-1477:
---------------------------------------------
If you care to pick Gora trunk, package it and replace the 0.3 version which is
pulled with Nutch 2.2.1 then it will all work well... hopefully. You will also
need to compile the new databeans using the new schema prior to packaging. HTH,
please lt us know what happens.
Thanks
