![]() If you do not need them for troubleshooting of the jobs, you may want to delete them to reduce the storage cost. With on-demand HDInsight linked service, a HDInsight cluster is created every time a slice needs to be processed unless there is an existing live cluster ( timeToLive) and is deleted when the processing is done.Īs more activity runs, you see many containers in your Azure blob storage. HDInsight does not delete this container when the cluster is deleted. The HDInsight cluster creates a default container in the blob storage you specified in the JSON ( linkedServiceName). You can use a Script Action with the Azure HDInsight on-demand linked service.You are charged only for the time when the HDInsight cluster is up and running jobs.The clusterUserName, clusterPassword, clusterSshUserName, clusterSshPassword defined in your linked service definition are used to log in to the cluster for in-depth troubleshooting during the lifecycle of the cluster. The logs for jobs that are run on an on-demand HDInsight cluster are copied to the storage account associated with the HDInsight cluster.You are able to see the cluster in your Azure portal when the cluster is up and running. The on-demand HDInsight cluster is created under your Azure subscription.Note the following important points about on-demand HDInsight linked service: The storage account must be a general-purpose standard Azure Storage account. The cluster is created in the same region as the storage account (linkedServiceName property in the JSON) associated with the cluster. The service can automatically create an on-demand HDInsight cluster to process data. For more information, see Azure databricks linked service. Azure Databricks also supports on-demand jobs using job clusters. The on-demand configuration is currently supported only for Azure HDInsight clusters. You can create a linked service for the on-demand compute environment, configure it, and control granular settings for job execution, cluster management, and bootstrapping actions. It is automatically created by the service before a job is submitted to process data and removed when the job is completed. In this type of configuration, the computing environment is fully managed by the service. The Azure Storage linked service reference.Ī reference to the Azure SQL linked service that points to the HCatalog database. The on-demand HDInsight cluster is created by using the Azure SQL database as the metastore. The name of Azure SQL linked service that point to the HCatalog database. Specifies additional storage accounts for the HDInsight linked service so that the service can register them on your behalf.
