| Troubleshooting | L37-L132 | Diagnosing and fixing HDInsight cluster issues: creation/auth, networking, storage, Ambari/HDFS/Hive/HBase/Kafka/Spark/YARN problems, performance, disk/CPU, and known error codes/workarounds. |
| Best Practices | L133-L174 | Best practices for designing, securing, monitoring, scaling, and tuning HDInsight clusters and workloads (Hadoop, Spark, Hive, HBase, Kafka), including storage, migration, and performance optimization. |
| Decision Making | L175-L199 | Planning and migration guidance for HDInsight: sizing and performance, choosing storage/VMs/tools, upgrading versions/components, and moving Hadoop, HBase, Kafka, and configs to newer clusters. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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 |
| 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 |
