I meant that it could be a gora-mysql problem. In order to test it, you can run nutch in local mode with Generator Debug enabled.
Sorry, how do I run Nutch in local mode? I searched and find reference to http://wiki.apache.org/nutch/NutchTutorial in Nutch wiki but it wasn't helpful
if gora-mysql works properly, then you must see in the output, shouldFetch rejected url , fetchTime FetchTime curTime curTime for those urls that were fetched in the previous cycle.
Which output? haadop.log?
