Hi,
I'm a new nutch user. Currently I'm using Nutch 0.8.1. When I wanted to
start crawling according to the tutorial, I always get the following error:
Injector: starting
Injector: crawlDb: crawl2/crawldb
Injector: urlDir: urls
Injector: Converting injected urls to crawl db entries.
Exception in thread "main" java.io.IOException: Job failed!
at org.apache.hadoop.mapred.JobClient.runJob(JobClient.java:357)
at org.apache.nutch.crawl.Injector.inject(Injector.java:138)
at org.apache.nutch.crawl.Crawl.main(Crawl.java:105)
------------------------------------------------------------------------------------------------------------
From the log, I found a more detailed description which is:
2007-05-14 09:32:57,977 INFO crawl.Injector - Injector: starting
2007-05-14 09:32:57,978 INFO crawl.Injector - Injector: crawlDb:

... 3 more
At first I suspect that the error was caused by tomcat not running properly,
but after doing some checking I am confirmed that tomcat is indeed running.
Could somebody let me know what I might be doing wrong here?
Cheers,
