Summary
The documentation page demonstrates a bias toward Windows/Azure-centric tools by exclusively referencing Azure SQL Database as the external metastore solution, with no mention of Linux-native or open-source alternatives (such as MySQL, PostgreSQL, or on-premises SQL Server). There are no command-line examples (neither Windows nor Linux), but all configuration guidance assumes use of Azure Portal or Ambari UI, both of which are platform-agnostic but tightly coupled to Azure's ecosystem. There are no Linux-specific instructions or examples, and the documentation does not address scenarios outside of Azure SQL Database.
Recommendations
- Include examples of configuring external metastores using open-source databases commonly used in Linux environments, such as MySQL or PostgreSQL, which are supported by Hive and Oozie.
- Provide command-line examples for metastore configuration using Linux shell tools (e.g., using the Azure CLI, curl, or Hive/Oozie configuration files), not just portal or UI steps.
- Mention and document support for on-premises or self-hosted SQL Server, MySQL, or PostgreSQL as external metastores, if supported by HDInsight.
- Clarify whether the guidance applies only to Azure SQL Database or if other database engines are supported, and provide parity in documentation for those options.
- Add troubleshooting and configuration steps relevant to Linux-based deployments, such as firewall configuration using iptables or ufw, and database connectivity testing from Linux hosts.
