Error crawling URLs

[saloneerege]

I get an error in the Crawl log after starting the crawl as follows:

Can you do me a favor and type printenv in your terminal and paste the output?

My gut instinct here is that you do not have JAVA_HOME set on your path. There's some documentation on how to do this here: http://wiki.apache.org/nutch/NutchTutorial. Look at the "Verifying your Nutch Installation" section. I think you can ignore the part about messing with etc/hosts

I agree with Brittain, this looks symptomatic of JAVA_HOME not being set. I think this is something where Nutch itself could be more robust.
