Subject Map phase hanging for wordcount example
Date Tue, 06 Sep 2011 07:48:28 GMT
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
