Understanding Two-Digit and Three-Digit EEPs

Understanding the differences between the EEP directories on https://package.ezmeral.hpe.com/releases/MEP/ can help you prevent versioning issues.

To install or update a Ecosystem Pack (EEP), either manually or by using the Installer, you must first choose a EEP version. The EEP version that you choose has a corresponding subdirectory on https://package.ezmeral.hpe.com/releases/MEP/ from which the ecosystem packages are retrieved.
IMPORTANT To access the Data Fabric internet repository, you must specify the email and token of an HPE Passport account. For more information, see Using the HPE Ezmeral Token-Authenticated Internet Repository.
For each released EEP, the https://package.ezmeral.hpe.com/releases/MEP/ directory includes both two-digit and three-digit subdirectories:

The following table compares the two-digit and three-digit subdirectories and describes how they are used:

EEP Subdirectory Example Continuously Updated? Description
Two-digit MEP-3.0/ Yes Subdirectories using two digits (for example, MEP-3.0) contain the latest EEP and patches and are continuously updated. For example, if you select EEP 3.0 when using the Installer, the installer installs or upgrades your cluster with the packages from the most current version of EEP 3.0.x. If the most current version is EEP 3.0.1, EEP 3.0.1 is installed. If the most current version is EEP 3.0.2, EEP 3.0.2 is installed, and so on.

If you later decide to make changes to the cluster, the Installer applies the packages from the most current version, which can be different from the version you installed originally.

Two-digit EEP version numbers make new patches available automatically without the need for system reconfiguration.

Three-digit MEP-3.0.0/ No Subdirectories using three digits contain a fixed EEP version, including patches, and are not continuously updated. For example, if you select EEP 3.0.0 when using the Installer, the installer uses the packages from the MEP-3.0.0 subdirectory and continues to use the MEP-3.0.0 subdirectory until you change the specified EEP version.

Three-digit EEP version numbers ensure that your cluster uses only the specified EEP version. They are best for users who install software manually and do not require automatic updates.

MapR Installer Use of Two-Digit and Three-Digit EEPs

Installer version 1.5 automatically uses two-digit EEPs. Installer versions 1.6 and later use three-digit EEP versions and do not allow you to select two-digit EEPs.

Upgrades from Installer 1.5 to 1.6 or later

If you upgrade the Installer from version 1.5 to a later version, you see both two-digit and three-digit EEPs in the EEP drop-down list for an Incremental Install. The two-digit EEPs continue to operate as they did previously, installing the latest three-digit EEP with the same first two digits. The three-digit EEPs operate as described earlier on this page. Installer version 1.7 displays and supports only three-digit EEPs.
NOTE If your cluster uses two-digit EEPs, recommends that you upgrade to three-digit EEPs as soon as it is convenient to do so. Doing so enables you to use new features such as the "Extend Cluster" feature without introducing EEP version inconsistencies. You can upgrade by performing an Incremental Install and selecting a three-digit EEP.
