Cluster Permissions

The following table lists the actions a user can perform on a cluster, and the corresponding codes used in the cluster ACL:

Code	Allowed Action
login	Log in to the MapR Control System, use the API and command-line interface, read access on cluster and volumes
ss	Start/stop services
cv	Create volumes
a	Administrative access (can edit and view ACLs, but cannot perform cluster operations)
fc	Full control over the cluster (this enables all cluster-related administrative options with the exception of changing the cluster ACLs)
