Hi Neeraj,
This error doesn't look to be kerberos related initially. Can you
verify if 192.168.49.51
has the tasktracker process running?
Regards,
Robert

Hi All,
When hadoop started with Kerberos authentication hadoop fs commands work
well but MR job fails.
Simple wordcount program fails at reducer stage giving follwoing exception :
013-05-28 17:43:58,896 WARN org.apache.hadoop.mapred.
ReduceTask: attempt_201305281729_0003_r_00_1 copy failed:
Have you verified that the kerberos settings are configured properly in
mapred-site.xml too just as in hdfs-site.xml (assuming you are using MRv1)?

The error looks a little low level , network level . The http server for
some reason couldn't bind to the port.
Might have nothing to do with Kerborose.
Thanks,
Rahul
