Convert a Cluster from Root to Non-Root User

You can change a MapR cluster that runs as root to a non-root user. Non-root operation is available from MapR version 2.0 and later. In addition to converting the MapR user to a non-root user, you can also disable superuser privileges to the cluster for the root user for additional security.


You must perform these steps on all nodes on a stable cluster. Do not perform this procedure concurrently while upgrading packages.
