Nutch 1.8 on hadoop

[Ali Nazemian]

Hi,
I was wondering how can I run nutch 1.8 job on hadoop cluster? As far as
know for running nutch 1.7 job on hadoop cluster we could use
org.apache.nutch.crawl.Crawl class. Since this class was deprecated and
removed from nutch 1.8 what class would be responsible for crawling job?
Which class should I put in hadoop command?
Best regards.
