1---2name: azure-hdinsight3description: Expert knowledge for Azure HDInsight development including troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. Use when working with HDInsight Spark/Hive/Kafka/HBase clusters, Ambari, VNet networking, or Azure SQL/Cosmos DB integration, and other Azure HDInsight related development tasks. Not for Azure Synapse Analytics (use azure-synapse-analytics), Azure Databricks (use azure-databricks), Azure Stream Analytics (use azure-stream-analytics).4---5# Azure HDInsight Skill67This skill provides expert guidance for Azure HDInsight. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.89## How to Use This Skill1011> **IMPORTANT for Agent**: Use the **Category Index** below to locate relevant sections. For categories with line ranges (e.g., `L35-L120`), use `read_file` with the specified lines. For categories with file links (e.g., `[security.md](security.md)`), use `read_file` on the linked reference file1213> **IMPORTANT for Agent**: If `metadata.generated_at` is more than 3 months old, suggest the user pull the latest version from the repository. If `mcp_microsoftdocs` tools are not available, suggest the user install it: [Installation Guide](https://github.com/MicrosoftDocs/mcp/blob/main/README.md)1415This skill requires **network access** to fetch documentation content:16- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown.17- **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown.1819## Category Index2021| Category | Lines | Description |22|----------|-------|-------------|23| Troubleshooting | L37-L132 | Diagnosing and fixing HDInsight cluster issues:

newer clusters. |26| Architecture & Design Patterns | L200-L214 | HDInsight cluster architecture, security/VNet design, HA/DR and business continuity patterns, migration from on-prem Hadoop, shared storage, streaming (Spark/YARN), and Oozie-based pipelines. |27| Limits & Quotas | L215-L222 | Guidance on HDInsight capacity limits: log size/retention, supported cluster node sizes, external metastore constraints, and requesting/managing CPU core quota increases. |28| Security | L223-L266 | Securing HDInsight clusters: identity and access (Entra, LDAP, Ranger, RBAC), network isolation (NSG, Private Link), TLS/encryption, Kafka/Hive/Spark security, and security best practices. |29| Configuration | L267-L323 | Configuring and tuning HDInsight clusters: networking/VPN, Ambari/Hive/Spark/HBase settings, autoscale, monitoring/logging, SSH/Jupyter/VS Code access, and script-based customizations. |30| Integrations & Coding Patterns | L324-L391 | Patterns and code samples for integrating HDInsight (Hive, Spark, Kafka, HBase, MapReduce, Sqoop) with tools, SDKs, REST/CLI, and external services like SQL, Cosmos DB, Power BI, IoT, and Synapse |31| Deployment | L392-L405 | Creating, configuring, migrating, and automating HDInsight clusters (Hadoop, HBase, Kafka) using portal, CLI, PowerShell, ARM/REST, Data Factory, Marketplace, AMA, and runbooks |3233###
