We have the superuser group defined as 'supergroup' in our configuration. However, this goup does not exist in any of the nodes.
If I have to set up this group and start adding a couple of other accounts to have super usr access to hdfs, where should this Linux group be created? Should it be created in all nodes in the cluster? Or is it sufficient to create the Linux group in the Namenode hosts only?
