Deploy HDInsight on new Data Lake Store and Storage

Browse code

This template allows you to deploy a new Linux HDInsight cluster with new Data Lake Store and Storage accounts.

Prerequisites

PFX Certificate and Service Principal

In order to properly deploy this ARM template, you need to first create a service principal in your Azure Active directory.

This service principal needs to be configured to use a password-protected PFX certificate for authentication.

Below are instructions for creating the certificate and service principal.

1. Create a password-protected PFX certificate.

   In Windows, you can do this using Azure PowerShell.

    $certFolder = "C:\certificates"
    $certFilePath = "$certFolder\certFile.pfx"
    $certStartDate = (Get-Date).Date
    $certStartDateStr = $certStartDate.ToString("MM/dd/yyyy")
    $certEndDate = $certStartDate.AddYears(1)
    $certEndDateStr = $certEndDate.ToString("MM/dd/yyyy")
    $certName = "HDI-ADLS-SPI"
    $certPassword = "new_password_here"
    $certPasswordSecureString = ConvertTo-SecureString $certPassword -AsPlainText -Force
   
    mkdir $certFolder
   
    $cert = New-SelfSignedCertificate -DnsName $certName -CertStoreLocation cert:\CurrentUser\My -KeySpec KeyExchange -NotAfter $certEndDate -NotBefore $certStartDate
    $certThumbprint = $cert.Thumbprint
    $cert = (Get-ChildItem -Path cert:\CurrentUser\My\$certThumbprint)
   
    Export-PfxCertificate -Cert $cert -FilePath $certFilePath -Password $certPasswordSecureString
   

2. Create a service principal using the certificate.

   In Windows, you can do this using Azure PowerShell.

    $clusterName = "new-cluster-name-here"
    $certificatePFX = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2($certFilePath, $certPasswordSecureString)
    $credential = [System.Convert]::ToBase64String($certificatePFX.GetRawCertData())
   
    $application = New-AzureRmADApplication -DisplayName $certName `
                            -HomePage "https://$clusterName.azurehdinsight.net" -IdentifierUris "https://$clusterName.azurehdinsight.net"  `
                            -KeyValue $credential -KeyType "AsymmetricX509Cert" -KeyUsage "Verify"  `
                            -StartDate $certStartDate -EndDate $certEndDate
   
    $servicePrincipal = New-AzureRmADServicePrincipal -ApplicationId $application.ApplicationId
   

3. Obtain the service principal information needed for the ARM template deployment.

   In Windows, you can do this using Azure PowerShell.

   • Application ID: $servicePrincipal.ApplicationId
   • Object ID: $servicePrincipal.Id
   • AAD Tenant ID: (Get-AzureRmContext).Tenant.TenantId
   • Base-64 PFX file contents: [System.Convert]::ToBase64String((Get-Content $certFilePath -Encoding Byte))
   • PFX password: $certPassword
