Give comparision of Nutch Vs Heritrix

Question

I want to select one of the above for building a crawling framework for specific web sites. This is not an internet-wide crawl. I am not building a search index, and rather interested in scraping specific pages from the web site.

Could somebody please detail about the pros and cons of above? Thanks Nayn

Answer 1

Your main task is scrape specific pages from the web site.

Nutch : Open-source web-search software, built on Lucene Java

Heritrix : is the Internet Archive's open-source, extensible, web-scale, archival-quality web crawler project

So I think Heritrix is much better than Nutch for your project.

Learning a framework/library is a valuable exercise. But it takes some time. Since you task is not very complex one, sometimes it would be less painful to write a simple crawler from the scratch in Java
