Step 7: Bring Up the Cluster

The installation of software across a cluster of nodes will go more smoothly if the services have be pre-planned and each node has been validated. Referring to the cluster design developed in Planning the Cluster, ensure that each node has been prepared and meets the minimum requirements described in Preparing Each Node, and that the MapR packages have been installed on each node in accordance with the plan.

Bringing up the cluster involves setting up the administrative user, and installing a MapR license. Once these initial steps are done, the cluster is functional. You can use the MapR Control System Dashboard (MCS), or the MapR Command Line Interface (CLI), to examine nodes and activity on the cluster.
