Step 7: Bring up the Cluster

Ensure that you have prepared and validated each node.

The installation of software across a cluster of nodes will go more smoothly if the services have been 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 starting Zookeeper and Warden, installing a MapR license, and viewing the cluster installation status. Once these initial steps are done, the cluster is functional. You can use the MapR Control System (MCS) dashboard, or the MapR Command Line Interface (CLI), to examine nodes and activity on the cluster.
