Subject Re: Issues Running Hadoop 1.1.2 on multi-node cluster
Date Fri, 12 Jul 2013 00:16:44 GMT
I figured out the issue!

The problem was in the permission to rum Hadoop scripts from root user. I
create a dedicated hadoop user to rum hadoop cluster but one of the time i
accidentally started hadoop from root. Hence, some of the permissions of
hadoop scripts changed.

The solution is to again change the ownership of the hadoop folder to the
dedicated user using chown. Its working fine now.


Thanks a lot for the pointers!


Regards,
Siddharth
