CDH4 administration through one account
Hi,
I have a cluster CDH4. How can one perform hadoop admin without root access. Basically an account like 'john1' on the cluster want to have access to hdfs, mapred etc.,
Should 'john1' be included in the 'sudoers' file ?
What instructions should I ask System Admin team to have 'john1' access the hadoop accounts and perform hadoop admin realted activities.
Please advise.
Regards,
Raj

Hadoop don't use root privileges. But it has some built-in users and
groups like hdfs, mapred, etc. I think you should add your admin user at
least to groups hdfs and mapred.
