Add-AzHDInsightScriptAction

  • Reference
Module:
Az.HDInsight

Adds a script action to a cluster configuration object.

Syntax

Add-AzHDInsightScriptAction
   [-Config] <AzureHDInsightConfig>
   [-NodeType] <ClusterNodeType>
   [-Uri] <Uri>
   [-Name] <String>
   [[-Parameters] <String>]
   [-DefaultProfile <IAzureContextContainer>]
   [<CommonParameters>]

Description

The Add-AzHDInsightScriptAction cmdlet adds script actions to the HDInsight configuration object created by the New-AzHDInsightClusterConfig cmdlet. Script actions provide functionality that is used to install additional software or to change the configuration of applications that run on a Hadoop cluster by using Windows PowerShell or Bash scripts (for Windows or Linux clusters, respectively). A script action runs on the cluster nodes when HDInsight clusters are deployed, and they run after nodes in the cluster complete HDInsight configuration. The script action runs under system administrator account privileges and provides full access rights to the cluster nodes. You can provide each cluster with a list of script actions to run in a specified sequence.

Examples

Example 1: Add a script action to the cluster configuration object

# Primary storage account info
$storageAccountResourceGroupName = "Group"
$storageAccountResourceId = "yourstorageaccountresourceid"
$storageAccountName = "yourstorageacct001"
$storageAccountKey = (Get-AzStorageAccountKey -ResourceGroupName $storageAccountResourceGroupName -Name $storageAccountName)[0].value


$storageContainer = "container001"

# Script action info
$scriptActionName = "<script action name>"
$scriptActionURI = "<script action URI>"
$scriptActionParameters = "<script action parameters>" 

# Cluster configuration info
$location = "East US 2"
$clusterResourceGroupName = "Group"
$clusterName = "your-hadoop-001"
$clusterCreds = Get-Credential

# If the cluster's resource group doesn't exist yet, run:
#   New-AzResourceGroup -Name $clusterResourceGroupName -Location $location

# Create the cluster

                -Uri $scriptActionURI `

                -Name $scriptActionName `
                -Uri $scriptActionURI `
                -Parameters $scriptActionParameters `
                -NodeType Head `
            | New-AzHDInsightCluster `
                -ClusterType Hadoop `
                -OSType Windows `
                -ClusterSizeInNodes 4 `
                -ResourceGroupName $clusterResourceGroupName `
                -ClusterName $clusterName `
                -HttpCredential $clusterCreds `
                -Location $location `
                -StorageAccountResourceId $storageAccountResourceId `
                -StorageAccountKey $storageAccountKey `
                -StorageContainer $storageContainer

This command adds a script action for the Head and Worker nodes of the your-hadoop-001 cluster, to be run at the end of cluster creation.
