Install software on the hosts

If you have successfully registered the software repositories for the new target version with Ambari, you can now install the software on all hosts in the cluster.

Browse to Cluster Admin > Stack and Versions.
Click the Versions tab.
On a registered target version, click Install Packages and click OK to confirm.
The install version operation starts. This installs the target version on all hosts in the cluster. You can monitor the progress of the installation by clicking the Installing link. When the installation completes, the Upgrade button replaces the Install Packages button.
