 To learn more about deleting a cluster when it is no longer in use, see [Delete an HDInsight cluster using your browser, PowerShell, or the Azure CLI](https://docs.microsoft.com/azure/hdinsight/hdinsight-delete-cluster). We recommend that there be at least 30 to 60 minutes between the create and delete operation on a single cluster. Otherwise, the operation may fail and return the following error message:
 
-``Conflict (HTTP Status Code: 409) error when attempting to delete a cluster immediately after creation of a cluster. If you encounter this error, please wait until the newly created cluster is in operational state before attempting to delete it.``

 ### Can I upgrade the individual components that are pre-installed on the cluster?
 
 If you upgrade built-in components or applications that are pre-installed on your cluster, the resulting configuration will not 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 is not 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. This will cause component integration issues on your cluster.

 ### How can I estimate the size of a Hive metastore database?
 
-A Hive metastore is used to store the metadata for data sources that are used by the Hive server. Therefore, the size requirements are affected by the number of data sources you may have to use for the Hive and by how complex the data sources are. Therefore, the size cannot be estimated upfront. As outlined in [Hive metastore best practices](https://docs.microsoft.com/azure/hdinsight/hdinsight-use-external-metadata-stores#hive-metastore-best-practices), you can start at an S2 tier. This provides 50 DTU and 250 GB of storage. If you encounter a bottleneck, you can scale up the database.

 To join virtual machines to a domain, a domain controller is required. AAD-DS is the managed domain controller. It is considered an extension of AAD that provides all the Kerberos requirements to build a secure Hadoop cluster in a managed way. HDInsight as a managed service integrates with AAD-DS to provide the end-to-end security.

Also, ESP clusters will do some of the file system access control by using AAD at the cluster level when you use ADLS.
