Upgrade the Software

You can use the package manager to upgrade Flume or you can perform a manual install that keeps the prior version of Flume when installing a new version of Flume.

About this task

Flume installs into separate directories named after the version, such as /opt/mapr/flume/flume-<version>/, so the files for multiple versions can co-exist.

Procedure

  1. To upgrade with the package manager, run one of the following commands:
    • On RedHat and CentOS: 
      yum upgrade mapr-flume
    • On Ubuntu: 
      apt-get install mapr-flume
  2. To keep a prior version and install a newer version (manual installation), perform the following steps:
    • On RedHat and CentOS:
      1. Download the RPM package file for the mapr-flume version you want to install from http://package.mapr.com/releases/ecosystem-all/.
      2. Install the package with rpm.
        rpm -i --force mapr-flume-<version>.rpm
    • On Ubuntu:

      This process is not supported on Ubuntu, because apt-get and dpkg cannot manage multiple versions of a package with the same name.

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/).
