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 building Hive/Spark/Kafka/HBase jobs, tuning clusters, securing access, or integrating SQL, Cosmos DB, or Synapse, and other Azure HDInsight related development tasks. Not for Azure Databricks (use azure-databricks), Azure Synapse Analytics (use azure-synapse-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 file1213This skill requires **network access** to fetch documentation content:14- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch`. Returns Markdown.15- **Fallback**: Use `WebFetch`. Returns Markdown.1617## Category Index1819| Category | Lines | Description |20|----------|-------|-------------|21| Troubleshooting | L33-L128 | Diagnosing and fixing HDInsight cluster issues:

designing, securing, monitoring, scaling, and tuning HDInsight clusters and workloads (Hadoop, Spark, Hive, HBase, Kafka), including storage, migration, and performance optimization. |23| Decision Making | L171-L195 | Planning and migration guidance for HDInsight: cluster sizing, storage and VM selection, HBase/Kafka upgrades, version moves, and retiring or reconfiguring existing deployments. |24| Architecture & Design Patterns | L196-L211 | HDInsight cluster architecture, security, networking, HA/DR, migration from on-prem Hadoop, shared storage, streaming design, and operational pipelines with Ambari/Oozie |25| Limits & Quotas | L212-L221 | HDInsight capacity limits, node configs, Kafka-specific limits, metastore constraints, log sizing/retention, and how to request/manage CPU core quota increases. |26| Security | L222-L265 | 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. |27| Configuration | L266-L322 | Configuring and tuning HDInsight clusters: networking/VPN, Ambari/Hive/Spark/HBase settings, autoscale, monitoring/logging, SSH/Jupyter/VS Code access, and script-based customizations. |28| Integrations & Coding Patterns | L323-L390 | 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 |29| Deployment | L391-L404 | Creating, configuring, migrating, and automating HDInsight clusters (Hadoop, HBase, Kafka) using portal, CLI, PowerShell, ARM/REST, Data Factory, Marketplace, AMA, and runbooks |3031### Troubleshooting32| Topic | URL |33|-------|-----|34|
