Score Updating error in nutch
===

I stuck in 9th step of [this][1] tutorial.
When I enter the command java saying that There isn't any ScoreUpdater class.


sm@sm-N61Jq:~/Desktop/nutch-runtime-local-bin-$ ./nutch org.apache.nutch.scoring.webgraph.ScoreUpdater -crawldb crawl/crawldb -webgraphdb crawl/webgraphdb/
