5.2 Installation
This section contains information on installing and upgrading MapR. It also contains information on how to migrate data and applications from an Apache Hadoop cluster to a MapR cluster.
Upgrading MapR 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.
Upgrading MapR Expansion Packs
Describes how to upgrade MapR Expansion Packs (MEP), either as part of a MapR Core upgrade or to take advantage of a new MEP for the current version of MapR Core.
Upgrading the MEP Without the MapR Installer
After you upgrade MapR core without using the MapR Installer, you need to upgrade ecosystems components with manual steps. First, verify that your repository is configured to use a MapR Expansion Pack (MEP) that is supported by your cluster version. Then, upgrade each component manually.
