Upgrading Hue

  Note:

To see which version of Hue 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 Hue from CDH 4 to CDH 5

  Note: Install Cloudera Repository

Before using the instructions on this page to install or upgrade, install the Cloudera yum, zypper/YaST or apt repository, and install or upgrade CDH 5 and make sure it is functioning correctly. For instructions, see CDH 5 Installation and the instructions for upgrading to CDH 5 .

If you have already removed Hue as part of your upgrade to CDH 5, skip to Installing and Configuring Hue.

Step 1: Stop the Hue Server

See Starting and Stopping the Hue Server.

Step 2: Uninstall the Old Version of Hue

  • On RHEL systems:
$ sudo yum remove hue-common
  • On SLES systems:
$ sudo zypper remove hue-common
  • On Ubuntu or Debian systems:
sudo apt-get remove hue-common

Step 3: Install Hue 3.x

Follow the instructions under Installing Hue.

  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.

Step 4: Start the Hue Server

See Starting and Stopping the Hue Server.

Upgrading Hue from an Earlier CDH 5 Release

You can upgrade Hue either as part of an overall upgrade to the latest CDH 5 release (see Upgrading from a CDH 5 Beta Release to the Latest Release ) or independently. To upgrade Hue from an earlier CDH 5 release to the latest CDH 5 release, proceed as follows.

Step 1: Stop the Hue Server

See Starting and Stopping the Hue Server.

  Warning:

You must stop Hue. If Hue is running during the upgrade, the new version will not work correctly.

Step 2: Install the New Version of Hue

Follow the instructions under Installing Hue.

  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.

Step 3: Start the Hue Server
