A fullscreen control adds a button to toggle the map or specified HTML element between fullscreen and normal view. The following code sample creates an instance of the [FullscreenControl] class and adds it to the top-right corner of the map.

Multiple controls can be put into an array and added to the map all at once and positioned in the same area of the map to simplify development. The following code snippet adds the standard navigation controls to the map using this approach.

If you upgrade built-in components or applications that are pre-installed on your cluster, the resulting configuration won't be supported by Microsoft. These system configurations have not been tested by Microsoft. Try to use a different version of the HDInsight cluster that may already have the upgraded version of the component pre-installed.

For example, upgrading Hive as an individual component isn't supported. HDInsight is a managed service, and many services are integrated with Ambari server and tested. Upgrading a Hive on its own causes the indexed binaries of other components to change, and will cause component integration issues on your cluster.

To join VMs to a domain, you must have a domain controller. Microsoft Entra Domain Services is the managed domain controller, and is considered an extension of Microsoft Entra ID. Microsoft Entra Domain Services provides all the Kerberos requirements to build a secure Hadoop cluster in a managed way.
