MapR 5.0 Documentation : Setting the Administrative User

The administrative user has full control over the cluster, and can assign permissions for other users to manage aspects of the cluster.

To give full administrative control to a user

  1. Log on to any cluster node as root (or use sudo for the following command).
  2. Execute the following command, replacing <user> with the username of the account that will get administrative control:
    sudo /opt/mapr/bin/maprcli acl edit -type cluster -user <user>:fc

For general information about users and groups in the cluster, see Managing Users and Groups.
