Upgrading Mahout

  Note:

To see which version of Mahout is shipping in CDH 5, check the Version and Packaging Information. For important information on new and changed components, see the CDH 5 Release Notes.

Upgrading Mahout from CDH 4 to CDH 5

To upgrade Mahout to CDH 5, you must uninstall the CDH 4 version and then install the CDH 5 version. Proceed as follows.

Step 1: Remove CDH 4 Mahout

To remove Mahout on a Red Hat system: 

$ sudo yum remove mahout

To remove Mahout on a SLES system: 

$ sudo zypper remove mahout

To remove Mahout on an Ubuntu or Debian system: 

$ sudo apt-get remove mahout

Step 2: Install CDH 5 Mahout

See Installing Mahout.

  Important: Configuration files
  • If you install a newer version of a package that is already on the system, configuration files that you have modified will remain intact.
  • If you uninstall a package, the package manager renames any configuration files you have modified from <file> to <file>.rpmsave. If you then re-install the package (probably to install a new version) the package manager creates a new <file> with applicable defaults. You are responsible for applying any changes captured in the original configuration file to the new configuration file. In the case of Ubuntu and Debian upgrades, you will be prompted if you have made changes to a file for which there is a new version; for details, see Automatic handling of configuration files by dpkg.

Upgrading Mahout from an Earlier CDH 5 Release to the Latest CDH 5 Release
