reduce-side join
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.
Cheers
