Installing without the MapR Installer

Describes how to install MapR software and ecosystem components manually.

These steps describe how to install a secure MapR cluster. If your cluster does not need to be secure, you can still use this procedure and skip over the steps indicated for security.

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 Ecosystem components, such as Hive, after you bring up the cluster.

Warning: Before you install, make sure that all nodes meet the requirements for installation. See Preparing each Node for more information. Failure to prepare nodes is the primary cause of installation problems.

You must also make sure that the MapR Installer package dependencies are installed. These packages are downloaded for you when you use the MapR Installer, but must be installed manually before you install without using the MapR Installer.

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.
Note: For information about repositories and packages for MapR software and Hadoop Ecosystem tools, see MapR Repositories and Packages.

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