Subject Reduce-side join
Date Tue, 29 Jun 2010 17:39:42 GMT
Hello everyone,

I am trying to use the hadoop's default 
reduce-side join. I want to use the TaggedMapOutput, DataJoinMapperBase, and DataJoinReducerBase
classes. I have added the hadoop's datajoin jar file in my build path but still i get the
following runtime error:

java.lang.NoClassDefFoundError: org/apache/hadoop/contrib/utils/join/TaggedMapOutput

Where possibly is the error? Please guide me.
