MapR 5.2 is at End of Life (EOL) and no longer supported. Please see the latest documentation. This documentation is not being updated.

Home
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.

Upgrading Flume

This section describes how to upgrade Flume without the MapR Installer.

About this task

Flume installs into separate directories named after the version, such as /opt/mapr/flume/flume-<version>/.

Procedure

To upgrade with the package manager, run one of the following commands:

On RedHat and CentOS:

yum update mapr-flume

On Ubuntu:

apt-get install mapr-flume

On SUSE:

zypper update mapr-flume

What to do next

To apply custom configurations to the new version, migrate any custom configuration settings into the new default files in the conf directory (/opt/mapr/flume/flume-<version>/conf/). See Post-Upgrade Steps for Flume.
