Mount Point: /api/v12/clusters/{clusterName}/commands/upgradeCdh


Perform CDH upgrade to the specified version.

Allows the following upgrades:

If using packages, CDH packages on all hosts of the cluster must be manually upgraded before this command is issued.

The command will upgrade the services and their configuration to the version available in the CDH5 distribution.

Unless rolling upgrade options are provided, the entire cluster will experience downtime. If rolling upgrade options are provided, command will do a "best-effort" rolling upgrade of the given cluster, i.e. it does plain upgrade of services that cannot be rolling upgraded, followed by first rolling upgrading non-slaves and then rolling restarting the slave roles of services that can be rolling restarted. The slave restarts are done host-by-host.

Available since v9. Rolling upgrade is only available with Cloudera Manager Enterprise Edition. A more limited upgrade variant available since v6.
