Looks like you have hit this issue. Either apply the patch or download the fixed version, and you should be good to go.

i have gone through the link Closed upon release of Hadoop 1.2.0. i am using 1.2.0 only , so can i re-install all the set up with higher version...?@Disunite – Damsel

i do got this error in my master task tracker log 2013-07-25 15:23:54,236 ERROR org.apache.hadoop.mapred.TaskTracker: Caught exception: java.io.IOException: Call to master/192.168.0.1:54311 failed on local exception: java.io.IOException: Connection reset by peer – Damsel

facing this error 2013-07-25 19:41:11,765 WARN org.apache.hadoop.security.UserGroupInformation: No groups available for user webuser 2013-07-25 19:41:11,778 WARN org.apache.hadoop.security.ShellBasedUnixGroupsMapping: got exception trying to get groups for user webuser org.apache.hadoop.util.Shell$ExitCodeException: id: webuser: No such user – Damsel

Sorry, I don't know how did I miss the last comment. Did you notice this : webuser: No such user?? – Disunite

np:-) Yes this says no such user, how can i comment this..? – Damsel

can i replace this web user with my machine user , hduser – Damsel

Yes. Replace it in hdfs-site.xml. – Disunite

This is the related JIRA - issues.apache.org/jira/browse/HADOOP-5146 . It looks exactly like the your issue, rather than the one I have specified above. But this was fixed long ago. Are you on windows, BTW?? – Disunite

no i am using fedora, both my machines are of same OS , yes they looks same , but i am using 1.2.0 @ Tariq – Damsel
