Major Description
Since learning that nutch will be unable to crawl the javascript function calls in href, I started looking for other alternatives. I decided to crawl http://en.wikipedia.org/wiki/Districts_of_India.
I first tried injecting this URL and follow the step-by-step approach till fetcher - when I realized, nutch did not fetch anything from this website. I tried looking into logs/hadoop.log and found the following 3 lines - which I believe could be saying that nutch is unable to parse the robots.txt in the website and ttherefore, fetcher stopped?

I tried checking the URL using parsechecker and no issues there! I think it means that the robots.txt is malformed for this website, which is preventing fetcher from fetching anything. Is there a way to get around this problem, as parsechecker seems to go on its merry way parsing.
