Selecting an Installer Version to Use

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

Choosing an Installer Version

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

However, the newer Installer versions do not support Release 5.x. You must use Installer or if your cluster is on a 5.x release. Installer is the last version of the Installer to support installation for Release 5.x. Installer 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 core, you must use Installer to perform the following operations:
  • New installs
  • Incremental installs
  • Patch installs
  • Maintenance updates
  • Extend-cluster operations

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

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

Special Considerations for Ubuntu 16.04 Clusters

As indicated in the 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.

Downloading Older Versions of the Installer

By default, the file provided in the installer-v<version>/ directories in 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
  1. Download the 1.17 or later version of See Installer.
  2. Add the following environmental variable to your current shell:
    export MAPR_INSTALLER_REPO_DIR=installer-v<version>
    The export command tells to install the Installer package from the directory you specify. For example, the following command causes to install the v1.11.0 Installer:
    export MAPR_INSTALLER_REPO_DIR=installer-v1.11.0 
  3. Run as described in Installer to install the Installer version you specified using the export command.
