Oct 1, 2025October 2025: Delivered Hierarchical Namespace (HNS) configuration controls for the Hadoop connectors in GoogleCloudDataproc/hadoop-connectors. Introduced two new configuration flags: (1) enable native HNS APIs for rename and delete operations, and (2) enable performance optimizations for HNS-enabled buckets, providing granular control and potential throughput improvements. Documentation updated to reflect the new flags (commit a1b79b5608171330b96f0c9960a80e560c14c198, "Add HNS flags to configuration.md (#1529)"). This work strengthens data governance, operational control, and performance readiness for customers leveraging HNS.

Sep 1, 2025Month: 2025-09 — Delivered targeted features and reliability improvements for the GoogleCloudDataproc/hadoop-connectors, with a focus on business value and system performance. Implemented default-enabled move operation for rename in the Google Cloud Storage Hadoop connector, updated integration tests to validate move usage and fallback to copy-then-delete when disabled, and un-ignored the move operation test to ensure end-to-end coverage. Added hierarchical namespace (HNS) optimizations including native folder creation/retrieval and recursive folder creation, plus enhancements to list, rename, and delete for HNS-enabled buckets. These changes position the connector for faster, more cost-effective object operations and stronger HNS support in production.
