6.1 Installation
This section contains information about installing and upgrading MapR software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a MapR cluster.
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.
Upgrading MapR Ecosystem Packs
Describes how to upgrade MapR Ecosystem Packs (MEPs), 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 MapR Ecosystem Pack Without the MapR Installer
After you upgrade MapR core without using the MapR Installer, you need to upgrade ecosystem components with manual steps. First, verify that your repository is configured to use a MapR Ecosystem Pack (MEP) that is supported by your cluster version. Then, upgrade each component manually.
