To provide more authentication options, HDInsight Tools for VSCode now can be connected to HDInsight cluster through Ambari for job submissions. You can easily link (HDInsight: Link a cluster) or unlink (HDInsight: Unlink a cluster) a normal cluster by using Ambari managed username and password, which is independent of your Azure signing process. The Ambari connection applies to Spark and Hive clusters in all the Azure environments which host HDInsight services.
To support HDInsight Enterprise Secure Package (in preview), you can also connect to the secured cluster through domain username (e.g. firstname.lastname@example.org). This connection is applicable for both traditional blob storage (WASB) or Azure Data Lake Storage (ADLS) as underlying storage. Once you connect to the secured HDInsight cluster, you can use the signed in domain credentials for all you job submissions.
This addition grants you more flexibilities to connect to your HDInsight clusters in addition to your Azure subscriptions and greatly simplify your experiences in submitting your Hive and Spark jobs.

- Open the command palette by selecting CTRL+SHIFT+P, and then enter HDInsight: Link a cluster.
- Enter HDInsight cluster URL -> input Username -> input Password -> select cluster type – –> Link success confirmation message. Now you can submit your hive / spark query or job to this linked cluster.
Please note that you can use either Ambari username / pwd or Secure Hadoop domain username / pwd to connect.
