Installing MapR Software

After you have planned the cluster and prepared each node, you can install the MapR distribution from the MapR repository or package files. Installing MapR requires that you perform certain steps on each node. You can install Apache Hadoop components, such as HBase or Hive after you bring up the cluster. It is usually easier to bring up the MapR Hadoop cluster successfully before you install Hadoop ecosystem components.

WARNING: Before you install, make sure that all nodes meet the requirements for installation by preparing each node.

Failure to prepare nodes is the primary cause of installation problems. You must also have the following information from your cluster plan when you install:

A list of the hostnames (or IP addresses) for all nodes and the services that you want to run on each node.
A list of all disks and/or partitions to use on each node.

To successfully install MapR, complete each step described in subsequent sections.
