HDP upgrade checklist

You must ensure that your HDP cluster satisfies specific prerequisites before initiating the upgrade process.

  • 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.
