Upgrading MapR Core or MEP Components

Depending on your current configuration, you may choose to upgrade the MapR version (MapR Core), ecosystem components, clients, or MapR Monitoring components.

Getting Started with Upgrades

Most upgrades involve moving from one version of MapR Core to another version and upgrading MapR Expansion Pack (MEP) components at the same time. To learn about the different methods you can use to execute this kind of upgrade, see Upgrade Workflows.

Upgrading a MapR Expansion Pack (MEP)

To upgrade an ecosystem component, you must upgrade the MEP to which it belongs. MEPs can be upgraded when you upgrade MapR Core or independently of a MapR Core upgrade. If your MapR Core release supports multiple MEP versions, you might be able to upgrade to a different MEP without upgrading MapR Core. See MEP Support by MapR Core Version.

If a component is supported by your current MEP, you can add the component at any time by using manual steps or the Incremental Install function of the MapR Installer. See Upgrading MapR Expansion Packs.

Upgrading MapR Clients

The MapR Client is a part of MapR Core. You upgrade MapR client nodes after you upgrade the MapR cluster nodes but before enabling new features. See Planning Upgrades to MapR Clients.

Upgrading MapR Monitoring

MapR Monitoring components are available as part of the MapR Expansion Pack (MEP) that you selected for the cluster. Once MapR Monitoring is installed, you can upgrade MapR Monitoring components as part of the MEP upgrade process. You can upgrade a MEP without having to upgrade MapR Core, provided the MEP you plan to upgrade to is supported by the current release. See Upgrading MapR Expansion Packs.
