Hi Folks, I am working on a 3 node cluster (1 NN + 2 DNs) . I loaded some test data with replication factor 3 (around 400MB data). However when I run wordcount example , it hangs at map 0%.
bin/hadoop jar hadoop-examples-0.20.3-SNAPSHOT.jar wordcount /test_data /out2 11/09/06 13:07:28 INFO input.FileInputFormat: Total input paths to process : 2 11/09/06 13:07:28 INFO mapred.JobClient: Running job: job_201109061248_0002 11/09/06 13:07:29 INFO mapred.JobClient: map 0% reduce 0% TTs and DNs are running fine on my slaves . I see them running when I run jps command. Can any one help me out on this? Any idea why this would happen? I am totally clueless as nothing shows up in logs too.! Thanks, jS
