Upgrading an HDF Cluster

Prerequisites
To perform an HDF upgrade using Ambari, your cluster must meet the following prerequisites. These prerequisites are required because they allow Ambari to know whether the cluster is in a healthy operating mode and can be successfully managed from Ambari.
Registering Your Target Version
Registering your target version makes Ambari aware of the Cloudera stack to which you want to upgrade, provides the public repository location, and specifies your public or private repository delivery preference.
Installing Your Target Version
Installing your target version downloads the public repositories containing software packages for your target version onto each node in your cluster.
Upgrade HDF
Upgrading HDF installs your target software version onto each node in your cluster. You can perform either an express or a rolling upgrade.
Start Ambari LogSearch and Metrics
After you have upgraded your HDF cluster, you should ensure that Ambari LogSearch and Metrics are both running.
