Step 3: Install MapR Service Packages

Install services based on your cluster plan and service layout. Depending on your plan, you may have decided to run your cluster in one of the following modes:

  • MapReduce Classic (MapReduce1)
  • YARN (MapReduce2)
  • Mixed-Mode (MapReduce1 and MapReduce2)

List of Packages by Mode

The following table lists the MapR packages to install on cluster nodes based on the MapReduce mode that you plan to run:

Warning: This table is a rough guide and does not include the additional packages required for internal dependencies or Hadoop ecosystem components.

Install the packages based on a thorough plan. As a best practice, do not install mapr-tasktracker or mapr-nodemanager on nodes with CLDB and/or ZooKeeper installed.

To install MapR, select one of the installation methods in the subsequent topics, depending on your operating system.
