Converting a Cluster from Root to Non-Root User from the Command-Line
You can change a MapR cluster that runs as root
to a non-root user. 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.
WARNING: You must perform these steps on all nodes on a stable cluster. Do not
perform this procedure concurrently while upgrading packages.
