Bias Analysis
Bias Types:
⚠️
powershell_heavy
⚠️
windows_first
⚠️
missing_linux_example
Summary:
The documentation page demonstrates a Windows bias by providing only PowerShell automation examples for DNS setup and referencing PowerShell first when describing how to create a cluster. There are no equivalent Bash or Azure CLI script examples for Linux users, and the PowerShell approach is presented as the primary method for automation.
Recommendations:
- Provide equivalent Bash/Azure CLI script examples for DNS automation tasks, ensuring Linux users can follow along without needing PowerShell.
- When referencing how to create a cluster, mention Azure CLI and ARM templates before or alongside PowerShell, not after.
- Add explicit Linux/macOS guidance or notes where automation or scripting is discussed, clarifying that all steps can be performed cross-platform.
- Where possible, use cross-platform tools (e.g., Azure CLI, ARM templates) in code examples, or provide parallel examples for both Windows (PowerShell) and Linux (Bash/CLI).

<#
This script is an example to help you get started with automation and can be adjusted based on your needs.
This script assumes:
- The HDInsight cluster has already been created, and the context where this script is run has permissions to read/write resources in the same resource group.
- The private DNS zone resource exists in the same subscription as the HDInsight cluster.
We recommend that you use the latest version of the Az.HDInsight module.

$subscriptionId = "<Replace with subscription for deploying HDInsight clusters, and containing private DNS zone resource>"
$clusterName = "<Replace with cluster name>"
$clusterResourceGroupName = "<Replace with resource group name>"
# For example, azurehdinsight.net for public cloud.
$dnsZoneName = "<Replace with private DNS zone name>"
$dnsZoneResourceGroupName = "<Replace with private DNS zone resource group name>"
