Function Add-DatabricksCluster { <# .SYNOPSIS Creates a new Spark cluster. This method acquires new instances from the cloud provider if necessary. This method is asynchronous; the returned cluster_id can be used to poll the cluster state. When this method returns, the cluster is in a PENDING state. The cluster is usable once it enters a RUNNING state. See ClusterState. You can either specify all single properties of the cluster on your own or provide a cluster object that contains all the properties. Single properties will overwrite the values in the cluster object! .DESCRIPTION Creates a new Spark cluster. This method acquires new instances from the cloud provider if necessary. This method is asynchronous; the returned cluster_id can be used to poll the cluster state. When this method returns, the cluster is in a PENDING state. The cluster is usable once it enters a RUNNING state. See ClusterState. Official API Documentation: https://docs.databricks.com/api/latest/clusters.html#create .PARAMETER ClusterObject A PowerShell object representing the definition of a cluster according to Databricks documentation. .PARAMETER NumWorkers Number of worker nodes that this cluster should have. A cluster has one Spark Driver and num_workers Executors for a total of num_workers + 1 Spark nodes. Note: When reading the properties of a cluster, this field reflects the desired number of workers rather than the actual current number of workers. For instance, if a cluster is resized from 5 to 10 workers, this field will immediately be updated to reflect the target size of 10 workers, whereas the workers listed in spark_info will gradually increase from 5 to 10 as the new nodes are provisioned. .PARAMETER MinWorkers The minimum number of workers to provision for this autoscale-enabled cluster. .PARAMETER MaxWorkers The maximum number of workers to provision for this autoscale-enabled cluster. .PARAMETER ClusterName Cluster name requested by the user. This doesn't have to be unique. If not specified at creation, the cluster name will be an empty string. .PARAMETER SparkVersion The Spark version of the cluster. A list of available Spark versions can be retrieved by using the List SparkVersions API call. This field is required. .PARAMETER SparkConf An object containing a set of optional, user-specified Spark configuration key-value pairs. You can also pass in a string of extra JVM options to the driver and the executors via spark.driver.extraJavaOptions and spark.executor.extraJavaOptions respectively. Example Spark confs: {"spark.speculation": true, "spark.streaming.ui.retainedBatches": 5} or {"spark.driver.extraJavaOptions": "-verbose:gc -XX:+PrintGCDetails"} .PARAMETER AwsAttributes Attributes related to clusters running on Amazon Web Services. If not specified at cluster creation, a set of default values will be used. .PARAMETER NodeTypeId This field encodes, through a single value, the resources available to each of the Spark nodes in this cluster. For example, the Spark nodes can be provisioned and optimized for memory or compute intensive workloads A list of available node types can be retrieved by using the List Node Types API call. This field is required. .PARAMETER DriverNodeTypeId The node type of the Spark driver. Note that this field is optional; if unset, the driver node type will be set as the same value as node_type_id defined above. .PARAMETER InstancePoolId The optional ID of the instance pool to which the cluster belongs. Refer to Instance Pools API for details. .PARAMETER DriverInstancePoolId The optional ID of the instance pool to which the cluster belongs. Refer to Instance Pools API for details. .PARAMETER SshPublicKeys SSH public key contents that will be added to each Spark node in this cluster. The corresponding private keys can be used to login with the user name ubuntu on port 2200. Up to 10 keys can be specified. .PARAMETER CustomTags Additional tags for cluster resources. Databricks will tag all cluster resources (e.g., AWS instances and EBS volumes) with these tags in addition to default_tags. Notes: Tags are not supported on legacy node types such as compute-optimized and memory-optimized Databricks allows at most 45 custom tags .PARAMETER ClusterLogConf The configuration for delivering Spark logs to a long-term storage destination. Only one destination can be specified for one cluster. If the conf is given, the logs will be delivered to the destination every 5 mins. The destination of driver logs is <destination>/<cluster-id>/driver, while the destination of executor logs is <destination>/<cluster-id>/executor. .PARAMETER InitScripts The configuration for storing init scripts. Any number of destinations can be specified. The scripts are executed sequentially in the order provided. If cluster_log_conf is specified, init script logs are sent to <destination>/<cluster-id>/init_scripts. $init_scripts = @( @{ "dbfs" = @{ "destination" = "dbfs:/databricks/my-init-script.sh"; }; } ) .PARAMETER SparkEnvVars An object containing a set of optional, user-specified environment variable key-value pairs. Key-value pairs of the form (X,Y) are exported as is (i.e., export X='Y') while launching the driver and workers. In order to specify an additional set of SPARK_DAEMON_JAVA_OPTS, we recommend appending them to $SPARK_DAEMON_JAVA_OPTS as shown in the example below. This ensures that all default databricks managed environmental variables are included as well. Example Spark environment variables: {"SPARK_WORKER_MEMORY": "28000m", "SPARK_LOCAL_DIRS": "/local_disk0"} or {"SPARK_DAEMON_JAVA_OPTS": "$SPARK_DAEMON_JAVA_OPTS -Dspark.shuffle.service.enabled=true"} .PARAMETER AutoterminationMinutes Automatically terminates the cluster after it is inactive for this time in minutes. If not set, this cluster will not be automatically terminated. If specified, the threshold must be between 10 and 10000 minutes. You can also set this value to 0 to explicitly disable automatic termination. .PARAMETER EnableElasticDisk Autoscaling Local Storage: when enabled, this cluster will dynamically acquire additional disk space when its Spark workers are running low on disk space. This feature requires specific AWS permissions to function correctly - refer to Autoscaling local storage for details. .PARAMETER PythonVersion Allows you to explicitly set the Python version for the cluster by adding the entry 'PYSPARK_PYTHON' to the SparkEnvVars parameter. Default is Python 2 (2.7) For details please refer to https://docs.azuredatabricks.net/user-guide/clusters/python3.html .EXAMPLE Add-DatabricksCluster -NumWorkers 2 -ClusterName "MyCluster" -SparkVersion "4.0.x-scala2.11" -NodeTypeId 'Standard_DS3_v2' #> [CmdletBinding()] param ( [Parameter(ParameterSetName = "FixedSize", Mandatory = $true)] [int32] $NumWorkers, [Parameter(ParameterSetName = "Autoscale", Mandatory = $true)] [int32] $MinWorkers, [Parameter(ParameterSetName = "Autoscale", Mandatory = $true)] [int32] $MaxWorkers, [Parameter(ParameterSetName = "ClusterObject", Mandatory = $true, ValueFromPipeline = $true)] [object] $ClusterObject, [Parameter(Mandatory = $false)] [string] $ClusterName, [Parameter(Mandatory = $false)] [hashtable] $SparkConf, [Parameter(Mandatory = $false)] [hashtable] $AwsAttributes, [Parameter(Mandatory = $false)] [string[]] $SshPublicKeys, [Parameter(Mandatory = $false)] [hashtable] $CustomTags, [Parameter(Mandatory = $false)] [object] $ClusterLogConf, [Parameter(Mandatory = $false)] [object[]] $InitScripts, [Parameter(Mandatory = $false)] [hashtable] $SparkEnvVars, [Parameter(Mandatory = $false)] [int32] $AutoterminationMinutes, [Parameter(Mandatory = $false)] [Nullable[bool]] $EnableElasticDisk, [Parameter(Mandatory = $false)] [string] [ValidateSet("2", "2 (2.7)", "3", "3 (3.5)")] $PythonVersion = "3", [Parameter(Mandatory = $false)] [string] [ValidateSet("HighConcurrency", "Standard", "SingleNode")] $ClusterMode ) DynamicParam { #Create the RuntimeDefinedParameterDictionary $Dictionary = New-Object System.Management.Automation.RuntimeDefinedParameterDictionary $nodeTypeIdValues = (Get-DynamicParamValues { Get-DatabricksNodeType }).node_type_id New-DynamicParam -Name NodeTypeId -ValidateSet $nodeTypeIdValues -DPDictionary $Dictionary New-DynamicParam -Name DriverNodeTypeId -ValidateSet $nodeTypeIdValues -DPDictionary $Dictionary $instancePoolValues = (Get-DynamicParamValues { Get-DatabricksInstancePool }).instance_pool_id New-DynamicParam -Name InstancePoolId -ValidateSet $instancePoolValues -Alias "instance_pool_id" -DPDictionary $Dictionary New-DynamicParam -Name DriverInstancePoolId -ValidateSet $instancePoolValues -Alias "driver_instance_pool_id" -DPDictionary $Dictionary $sparkVersionValues = (Get-DynamicParamValues { Get-DatabricksSparkVersion }).key New-DynamicParam -Name SparkVersion -ValidateSet $sparkVersionValues -DPDictionary $Dictionary #return RuntimeDefinedParameterDictionary return $Dictionary } begin { $requestMethod = "POST" $apiEndpoint = "/2.0/clusters/create" } process { $NodeTypeId = $PSBoundParameters.NodeTypeId $DriverNodeTypeId = $PSBoundParameters.DriverNodeTypeId $SparkVersion = $PSBoundParameters.SparkVersion #Set parameters Write-Verbose "Building Body/Parameters for final API call ..." if ($ClusterObject) { $parameters = $ClusterObject | ConvertTo-Hashtable Write-Verbose "ClusterObject: " Write-Verbose $($ClusterObject | ConvertTo-Json) } else { $parameters = @{} } if ($PythonVersion) { # check if a PythonVersion was explicitly specified if (-not $SparkEnvVars) { # ensure that the SparkEnvVars variable exists -

For instance, if a cluster is resized from 5 to 10 workers, this field will immediately be updated to reflect the target size of 10 workers, whereas the workers listed in spark_info will gradually increase from 5 to 10 as the new nodes are provisioned. .PARAMETER MinWorkers The minimum number of workers to provision for this autoscale-enabled cluster. .PARAMETER MaxWorkers The maximum number of workers to provision for this autoscale-enabled cluster. .EXAMPLE Resize-DatabricksCluster -ClusterID "1202-211320-brick1" -NumWorkers 10 #> [CmdletBinding()] param ( #[Parameter(Mandatory = $true, Position = 1, ValueFromPipelineByPropertyName = $true)] [Alias("cluster_id")] [string] $ClusterID, [Parameter(ParameterSetName = "FixedSize", Mandatory = $true, Position = 2)] [int32] $NumWorkers, [Parameter(ParameterSetName = "Autoscale", Mandatory = $true, Position = 2)] [int32] $MinWorkers, [Parameter(ParameterSetName = "Autoscale", Mandatory = $true, Position = 3)] [int32] $MaxWorkers ) DynamicParam { #Create the RuntimeDefinedParameterDictionary $Dictionary = New-Object System.Management.Automation.RuntimeDefinedParameterDictionary $clusterIDValues = (Get-DynamicParamValues { Get-DatabricksCluster }).cluster_id New-DynamicParam -Name ClusterID -ValidateSet $clusterIDValues -Alias 'cluster_id' -ValueFromPipelineByPropertyName -Mandatory -DPDictionary $Dictionary #return RuntimeDefinedParameterDictionary return $Dictionary } begin { $requestMethod = "POST" $apiEndpoint = "/2.0/clusters/resize" } process { $ClusterID = $PSBoundParameters.ClusterID Write-Verbose "Building Body/Parameters for final API call ..." #Set parameters $parameters = @{ cluster_id = $ClusterID } switch ($PSCmdlet.ParameterSetName) { "FixedSize" { $parameters | Add-Property -Name "num_workers" -Value $NumWorkers -Force } "Autoscale" { $parameters | Add-Property -Name "autoscale" -Value @{ min_workers = $MinWorkers; max_workers = $MaxWorkers } -Force } } $result = Invoke-DatabricksApiRequest -Method $requestMethod -EndPoint $apiEndpoint -Body $parameters return $result } } Function Remove-DatabricksCluster { <# .SYNOPSIS Permanently deletes a Spark cluster.
