Minimum Required Role:
Full
Administrator. This feature is not available when using Cloudera
Manager to manage Data Hub clusters.
The first time you log in to the
Cloudera Manager server after
upgrading your
Cloudera Manager software, the upgrade wizard runs. If
you did not complete the wizard at that time, or if you had hosts that
were unavailable at that time and still need to be upgraded, you can
re-run the upgrade wizard:
- Click the Hosts tab.
- Click Re-run Upgrade Wizard or Review Upgrade Status.
This takes you back through the installation wizard to upgrade Cloudera Manager Agents on your
hosts as necessary.
- Select the release of the Cloudera Manager Agent
to install. Normally, this is the Matched Release for this Cloudera Manager Server. However, if you used a custom repository
(instead of archive.cloudera.com) for the Cloudera Manager server,
select Custom Repository and provide the required information. The custom
repository allows you to use an alternative location, but that location must contain the
matched Agent version.
- Specify credentials and initiate Agent installation:
- Select root for the
root
account, or select Another
user and enter the username for an account that
has password-less sudo
privileges.
- Select an authentication method:
- If you choose password authentication, enter and confirm
the password.
- If you choose public-key authentication, provide a
passphrase and path to the required key files.
You can modify the default SSH port if
necessary.
- Specify the maximum number of host installations to run at
once. The default and recommended value is 10. You can adjust
this based on your network capacity.
- Click Continue.
When you click Continue, the Cloudera Manager
Agent is upgraded on all the currently managed hosts. You cannot search
for new hosts through this process. To add hosts to your cluster, click
the Add New Hosts to Cluster button.
