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 Ezmeral Ecosystem Pack (EEP), either manually or by using the MapR 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.
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
MapR 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 MapR 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 MapR
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 MapR software manually and do not require automatic updates. |
MapR Installer Use of Two-Digit and Three-Digit EEPs
MapR Installer version 1.5 automatically uses two-digit EEPs. MapR Installer versions 1.6 and later use three-digit EEP versions and do not allow you to select two-digit EEPs.
