Selecting an Installer Version to Use

Beginning with the MEP 6.2 release, several MapR Installer versions are available for use. The version that you select 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 MapR Ecosystem Packs (MEPs). To download the latest version, see Downloading the MapR Installer later on this page. For a list of recent Installer versions, see MapR Installer Updates.

However, MapR Installer and later provide minimal support for Release 5.2.x and lower versions. If your cluster runs Release 5.2.x or a lower version of MapR Core, you must use MapR Installer to perform the following operations:
  • New installs
  • Incremental installs
  • Patch installs
  • Maintenance updates
  • Extend-cluster operations

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

MapR Core Version Use This MapR Installer Version
5.1 Use Installer for all operations, including upgrades to Release 5.2.x. Note that you must upgrade to MapR 5.2.x with MEP 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 or later before upgrading.
5.2.x Use Installer 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 MEP 3.0.1 or later. Before upgrading, update the MapR Installer to or later.
6.x and later Use MapR Installer 1.12 or later for all operations.
