Thanks,

I've set up Hadoop on two machine and would like to test it with a simple test job. The setup/program works with single-node setup but not with the distributed environment. I get the following error when I run the simple org.myorg.WordCount program: 13/03/13 17:40:56 WARN mapred.JobClient: Use GenericOptionsParser for parsing the arguments. Applications should implement Tool for the same. 13/03/13 17:40:56 WARN mapred.JobClient: No job jar file set. User classes may not be found. See JobConf(Class) or JobConf#setJar(String). 13/03/13 17:40:56 INFO input.FileInputFormat: Total input paths to process : 3 13/03/13 17:40:56 INFO util.NativeCodeLoader: Loaded the native-hadoop library 13/03/13 17:41:07 INFO mapred.JobClient: Task Id : attempt_201303131649_0008_m_000004_0, Status : FAILED I'm not sure where the "permission denied" is actually caused. Do you have any hints? My user can access the HDFS formated space.
