Pinot Known Limitations

This page lists the known limitations observed during the Pinot setup.

• JDK Version Compatibility: Apache Pinot is running on JDK 11, while other Hadoop ecosystem components (e.g., HDFS, Hive) are running on JDK 8. This mismatch can lead to compatibility issues, especially during push operations to Pinot, as cross-JDK communication may not be fully supported or stable.
• Push Ingestion Failures: Due to the JDK version mismatch, push-based ingestion from components running on JDK 8 into Pinot (JDK 11) may fail or behave unpredictably.
• Ranger Integration: Apache Ranger integration is currently not supported with the current setup, limiting fine-grained access control and policy enforcement for Pinot.
• In ODP 3.2.3.x, the ZooKeeper UI Browser tab is non-functional through the Pinot UI.
