Upgrading MapR Core or EEP Components

Depending on your current configuration, you may choose to upgrade the release version (core), ecosystem components, clients, or monitoring components.

Getting Started with Upgrades

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

Upgrading an EEP

To upgrade an ecosystem component, you must upgrade the EEP to which it belongs. EEPs can be upgraded when you upgrade core or independently of a core upgrade. If your core release supports multiple EEP versions, you might be able to upgrade to a different EEP without upgrading core. See EEP Support and Lifecycle Status.

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

Upgrading MapR Clients

The MapR client is a part of core. You upgrade client nodes after you upgrade the 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 Ezmeral Ecosystem Pack (EEP) that you selected for the cluster. Once MapR Monitoring is installed, you can upgrade MapR Monitoring components as part of the EEP upgrade process. You can upgrade a EEP without having to upgrade core, provided the EEP you plan to upgrade to is supported by the current release. See Upgrading Ezmeral Ecosystem Packs.
