nutch doesnt run under 0.20.2+228-1~karmic-cdh3b1 version of hadoop
-------------------------------------------------------------------

                 Key: NUTCH-839
                 URL: https://issues.apache.org/jira/browse/NUTCH-839
             Project: Nutch
          Issue Type: Bug
          Components: fetcher
    Affects Versions: 1.1
         Environment: ubuntu linux version 2.6.31-14-server, x86_64 GNU/Linux
            Reporter: Robert Gonzalez


new versions of hadoop appear to put jars in a different format now, instead of file:/a/b/c/d/job.jar, its now jar:file:/a/b/c/d/job.jar!, which breaks nutch when its trying to load its plugins.  Specifically, the stack trace looks like:

Caused by: java.lang.RuntimeException: x point org.apache.nutch.net.URLNormalizer not found.
	at org.apache.nutch.net.URLNormalizers.<init>(URLNormalizers.java:124)
	at org.apache.nutch.crawl.Injector$InjectMapper.configure(Injector.java:57)

A simple test class was written the used the URLFilters class, and the following stack trace resulted:

10/07/01 14:25:25 INFO mapred.JobClient: Task Id : attempt_201006171624_46525_m_000000_1, Status : FAILED
java.lang.RuntimeException: org.apache.nutch.net.URLFilter not found.

	at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:142)
	at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:621)
	at org.apache.hadoop.mapred.MapTask.run(MapTask.java:305)
	at org.apache.hadoop.mapred.Child.main(Child.java:170)

Running this on an older version of hadoop works.
