Key: MAPREDUCE-1907 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1907 Project: Hadoop Map/Reduce Issue Type: Bug Components: tasktracker Affects Versions: 0.20.2 Environment: Linux 2.6.31-14-server #48-Ubuntu SMP Fri Oct 16 15:07:34 UTC 2009 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$InjectMapper.configure(Injector.java:57) A simple test class was written the used the URLFilters class, and the following stack trace resulted: 10/07/01 14:25:25 INFO mapred.JobClient: Task Id : attempt_201006171624_46525_m_000000_1, Status : FAILED java.lang.RuntimeException: org.apache.nutch.net.URLFilter not found. at org.apache.nutch.net.URLFilters.<init>(URLFilters.java:52) at com.maxpoint.crawl.BidSampler$BIdSMapper.setup(BidSampler.java:42) 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
