Hey guys, How we can make hadoop as multiuser ?
One way to think as whatever group we currently assigned to use hadoop, add users to same group and change permissions to hadoop.tmp.dir, mapred.system.dir, dfs.data.dir, and what not. I was playing on hadoop 0.20.205 and I observed we can't change the permission to the above mentioned folders.. If yes, what are the best practices for making hadoop as a multi user entity, specially for hadoop 0.20.205. Thanks, Praveenesh
