HDP upgrade checklist

You must ensure that your HDP cluster satisfies specific prerequisites before initiating the upgrade from Ambari 2.6.2.x to Ambari 7.1.x.x.

• You must review the Behavioral Changes.

• You must have root, administrative, or root-equivalent authorization on the Ambari Server host and all Ambari Agent hosts in the cluster.

• 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.

• You must disable the Queue Priority Support feature of YARN.
