I have installed Nutch 2.2.1 in Ubuntu 12.04 but on executing the command ./nutch crawl urls/ -dir download/ -depth 3 -topN 5
I get the following error:-
InjectorJob: Using class org.apache.gora.memory.store.MemStore as the Gora storage class. InjectorJob: total number of urls rejected by filters: 0 InjectorJob: total number of urls injected after normalization and filtering: 0 Exception in thread "main" java.lang.RuntimeException: job failed: name=generate: null, jobid=job_local1165582916_0002 at org.apache.nutch.util.NutchJob.waitForCompletion(NutchJob.java:54) at org.apache.nutch.crawl.GeneratorJob.run(GeneratorJob.java:199) at org.apache.nutch.crawl.Crawler.runTool(Crawler.java:68) at org.apache.nutch.crawl.Crawler.run(Crawler.java:152) at org.apache.nutch.crawl.Crawler.run(Crawler.java:250) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.nutch.crawl.Crawler.main(Crawler.java:257)
