Selecting an Installer Version to Use

Beginning with the EEP 6.2.0 release, several MapR Installer versions are available for use. The version that you use depends on your current MapR core version and whether or not you need to upgrade using the MapR Installer or Stanzas.

Choosing an Installer Version

In general, you should always use the latest available MapR Installer version. The latest MapR Installer version provides access to the latest Ezmeral Ecosystem Packs (EEPs). To download the latest version, see Installer Downloads later on this page. For a list of recent Installer versions, see MapR Installer Updates.

However, the newer MapR Installer versions do not support Release 5.x. You must use Installer 1.11.0.0 or 1.12.0.0 if your cluster is on a 5.x release. Installer 1.11.0.0 is the last version of the Installer to support installation for Release 5.x. Installer 1.12.0.0 is the last version of the installer to support upgrades from Release 5.2.x to Release 6.x.

If your cluster runs Release 5.2.x or a lower version of MapR core, you must use MapR Installer 1.11.0.0 to perform the following operations:
  • New installs
  • Incremental installs
  • Patch installs
  • Maintenance updates
  • Extend-cluster operations

This table describes how to select the MapR Installer version based on your current MapR software and your upgrade plans:

MapR Core Version Use This MapR Installer Version
6.x and later Except for Ubuntu 16.04 clusters, you may use the latest MapR Installer version for all operations. See the Special Considerations for Ubuntu 16.04 Clusters.
5.2.x Use Installer 1.11.0.0 until you need to upgrade to Release 6.x. To upgrade to Release 6.x using the MapR Installer, your cluster must have Release 5.2.x with EEP 3.0.1 or later. Before upgrading, update the MapR Installer to 1.12.0.0.
5.1 Use Installer 1.11.0.0 for all operations, including upgrades to Release 5.2.x. Note that you must upgrade to MapR 5.2.x with EEP 3.0.1 or later if you eventually want to upgrade to Release 6.x. After upgrading to 5.2.x, if you need to upgrade to Release 6.x, update the MapR Installer to 1.12.0.0 before upgrading.

Special Considerations for Ubuntu 16.04 Clusters

As indicated in the MapR Installer Support Matrix, Installer 1.17 and later are supported only on Ubuntu 18.04 and 20.04. If your cluster is installed on Ubuntu 16.04:
  • The Installer version that you can use depends on whether the Installer node is part of the cluster where you plan to install data-fabric software:
    If the Installer node is . . . Do this
    Part of the cluster Use Installer 1.16.0.x for all Installer operations.You cannot use Installer 1.17 or later unless you upgrade the cluster to Ubuntu 18.04 or 20.04.
    Not part of the cluster Use the latest Installer version on a node that is running any supported version of Ubuntu, RHEL or SLES to perform Installer operations on Ubuntu 16.04 nodes.
  • If you need to upgrade from core 6.1.x to core 6.2, you must first upgrade your operating system to Ubuntu 18.04 or 20.04 and then install Installer 1.17 or later to perform the core software upgrade.

Installer Downloads

This table summarizes download information for the MapR Installer:
Installer Version Download Location The mapr-setup.sh script provided in this location installs . . . .
Latest MapR Installer package.ezmeral.hpe.com/releases/installer/ The most current version of the MapR Installer
1.17.0.x package.ezmeral.hpe.com/releases/installer-v1.17 Installer 1.17.0.3
Installer 1.16.0.x package.ezmeral.hpe.com/releases/installer-v1.16 Installer 1.16.0.2
MapR Installer 1.12.0.0 package.ezmeral.hpe.com/releases/installer-v1.12.0 MapR Installer 1.12.0.0
MapR Installer 1.11.0.0 package.ezmeral.hpe.com/releases/installer-v1.11.0 MapR Installer 1.11.0.0

Downloading Older Versions of the Installer

By default, the mapr-setup.sh file provided in the installer-v<version>/ directories in http://package.ezmeral.hpe.com/releases/ installs the most current version of the Installer – and not the version for which the directory is named.

However, you can download older Installer versions by using the latest mapr-setup.sh:
  1. Download the 1.17 or later version of mapr-setup.sh. See MapR Installer.
  2. Add the following environmental variable to your current shell:
    export MAPR_INSTALLER_REPO_DIR=installer-v<version>
    The export command tells mapr-setup.sh to install the Installer package from the directory you specify. For example, the following command causes mapr-setup.sh to install the v1.11.0 Installer:
    export MAPR_INSTALLER_REPO_DIR=installer-v1.11.0 
  3. Run mapr-setup.sh as described in MapR Installer to install the Installer version you specified using the export command.
