Preparing to Upgrade Ambari
You must prepare to upgrade Ambari to 7.1.x.x. Review this section before you upgrade.
- You must have root, administrative, or root-equivalent authorization on the Ambari Server host and all Ambari Agent hosts in the cluster.
- You must backup the Ambari Server database.
- You must make a safe copy of the Ambari Server configuration file found at
/etc/ambari-server/conf/ambari.properties. - If your cluster is SSO-enabled, do not stop Knox before upgrading Ambari.
ambari-env.sh file is
overwritten and a backup copy of ambari-env.sh (with extension
.rpmsave) is created. If you have manually modified
ambari-env.sh (for example, to change Ambari Server heap), you must
re-apply your changes in the new file.
