Hello list, I have a hadoop cluster where I'd like to run nutch for crawling my repositories. I'm currently running cloudera's hadoop 0.20.2+737-1~lenny-cdh3b3 and nutch1.1 or nutch1.2. When I try to run:
$ hadoop jar build/nutch-1.2.job org.apache.nutch.crawl.Crawl /crawls/urls/ -depth 15 -dir /crawls/ -solr http://searchserver:8080/solr/ i get this exception: 10/10/28 12:22:21 WARN mapred.JobClient: Use GenericOptionsParser for parsing the arguments.
