Hi Alparslan, Thank you for the links. I am browsing through them to see what configuration is missed out that is leading to the rise of this exception.
As for what ever you mentioned expecting the reason for exception, I have had done everything, i.e, 1. You should uncomment the suitable Gora artifact lines at the end of [NUTCH_HOME]/conf/ivy.xml file. 2. Update the "gora.datastore.default" property in [NUTCH_HOME]/conf/gora.properties Since these steps are clearly mentioned in the wiki page I was referring too[1], it was done. So as I said, I have followed bit by bit, every configuration step mentioned in this link and after that is the error that I am getting.
