Summary
The documentation page demonstrates a Windows bias, especially in the certificate renewal section, where only PowerShell scripts and Windows-centric tools are provided for managing certificates and service principal credentials. There are no equivalent Bash, Linux CLI, or cross-platform Azure CLI examples for these critical operations. The troubleshooting steps for cluster access use generic commands (hdfs, curl) that are cross-platform, but the remediation steps for certificate management are exclusively Windows/PowerShell-focused.
Recommendations
  • Provide equivalent Bash or Azure CLI scripts for certificate creation, management, and assignment, suitable for Linux/macOS environments.
  • Include explicit instructions for Linux users on how to generate certificates (e.g., using openssl), associate them with service principals, and update HDInsight clusters.
  • When presenting scripts, offer both PowerShell and Bash/Azure CLI versions, or at least mention cross-platform alternatives.
  • Avoid assuming the user is on Windows; clarify which steps are OS-specific and provide parity for Linux users.
  • Reference Azure CLI documentation and commands alongside PowerShell cmdlets for all Azure resource management tasks.
