I may be having a setup issue with classpaths, would appreciate some help. I created a jar with all the Sample* classes in contrib/DataJoin. Here is the listing of my samplejoin.jar file: " zip.vim version v22 " Browsing zipfile /home/hadoop/hadoop_tests/samplejoin.jar " Select a file with cursor and press ENTER META-INF/ META-INF/MANIFEST.MF org/ org/apache/ org/apache/hadoop/ org/apache/hadoop/contrib/ org/apache/hadoop/contrib/utils/ org/apache/hadoop/contrib/utils/join/ org/apache/hadoop/contrib/utils/join/SampleDataJoinReducer.class org/apache/hadoop/contrib/utils/join/SampleTaggedMapOutput.class org/apache/hadoop/contrib/utils/join/SampleDataJoinMapper.class
When I go to run this, things start to run, but every Map try errors out with: "java.lang.RuntimeException: java.lang.ClassNotFoundException: org.apache.hadoop.contrib.utils.join.SampleTaggedMapOutput" Here is the command: hadoop jar ./samplejoin.jar org.apache.hadoop.contrib.utils.join.DataJoinJob datajoin/input datajoin/output Text 1 org.apache.hadoop.contrib.utils.join.SampleDataJoinMapper org.apache.hadoop.contrib.utils.join.SampleDataJoinReducer org.apache.hadoop.contrib.utils.join.SampleTaggedMapOutput Text This is a new install of 0.20.2. HADOOP_CLASSPATH is set to: /opt/hadoop-0.20.2/contrib/datajoin/hadoop-0.20.2-datajoin.jar Any help would be appreciated.
