parser not found exception

Hi,
When using bin/nutch, I see the following errors:

fetch of https://commerce.in.reuters.com/profile/pages/newsletter/begin.dofailed

How do I configure https protocol handler ?

Also, when I don't want to crawl previously crawled URLs, how do I clear
crawldb ?

Thanks
