Understanding the MEP Lifecycle

This page describes the MEP lifecycle and defines the lifecycle stages, which are Active, Deprecated, and Discontinued.

MEP Lifecycle Stages

HPE periodically releases new ecosystem components as ecosystem packs (MEPs). Each MEP is supported for 18 months. When new MEPs are released, older MEPs are deprecated or discontinued. Each MEP therefore has its own lifecycle.

As shown in the diagram, a MEP can transition through three lifecycle stages:
  • Active (12 months)
  • Deprecated (6 months)
  • Discontinued

The lifecycle stage determines if HPE issues updates and bug fixes for the MEP, which are reflected in changes to the major, minor, and maintenance versions of the MEP:

To view the current lifecycle status for every MEP, see MEP Support and Lifecycle Status.

MEP Versions

In HPE Ezmeral Data Fabric interfaces and documentation, Ecosystem Pack (MEP) versions are expressed as a dot-separated string of numbers having two or three places. For example:

A Change to This Version Typically Includes For Example
MEP major version A new MEP series that supports a new major, minor, or maintenance version of core. MEP Support and Lifecycle Status shows how MEP major versions change when new versions of core are introduced.
MEP minor version A significant change in features or APIs but no change in support for the current core version. MEPs 6.0.1 and 6.1.0 both support Release 6.1.0, but MEP 6.1.0 introduced new HPE Ezmeral Data Fabric Database features, such as the C# and Go OJAI clients, as well as new features for ecosystem components (Flume, Oozie, Tez, and Apache Kafka). MEP 6.2.0, which also supports Release 6.1.0, introduced new ecosystem component versions (Hue, Impala, Spark) and updated some components (Oozie and Hive).
MEP maintenance version Bug fixes only. MEP maintenance versions do not add new features or API changes and are backward compatible in the same MEP series. MEPs 5.0.3, 5.0.2, and 5.0.1 added bug fixes to the MEP 5.0.x line while preserving compatibility with Release 6.0.1.

Notification of Changes in Support for Released MEPs

To notify users about changes in MEP support, HPE issues periodic support advisories. When MEPs are deprecated or discontinued, users of those MEPs are encouraged to upgrade to newer MEPs.
