Upgrading Cloudera Manager

Upgrading Cloudera Manager enables new features of the latest product versions while preserving existing data and settings. Some new settings are added, and some additional steps may be required, but no existing configuration is removed.

Understanding Upgrades

The process for upgrading Cloudera Manager varies depending on the starting point. Categories of tasks to be completed include the following:
  • Install databases required for the release. In Cloudera Manager 5, the Host Monitor and Service Monitor roles use an internal database that provides greater capacity and flexibility. You do not need to configure an external database for these roles. If you are upgrading from Cloudera Manager 4, this transition is handled automatically. If you are upgrading a Free Edition installation and you are running a MapReduce service, you are asked to configure an additional database for the Activity Monitor that is part of Cloudera Express.
  • Upgrade the Cloudera Manager Server.
  • Upgrade the Cloudera Manager Agent. You can use an upgrade wizard that is invoked when you connect to the Admin Console or manually install the Cloudera Manager Agent packages.

Upgrading Cloudera Manager

You can upgrade from Cloudera Manager 5 to a later version of Cloudera Manager 5.
