PROFILE
Shohei Okumiya
Over four months, Okumin contributed to the apache/hive repository by delivering four robust features across data warehousing, security, and CI/CD automation. Okumin enhanced partition-aware joins and optimized test coverage for partitioned workloads using Java and SQL, improving query performance and correctness. They modernized Iceberg integration by aligning block location handling with the Iceberg library, reducing code duplication and easing future updates. Okumin also implemented OAuth2 authentication for the Iceberg REST Catalog in Hive Metastore, supporting JWT and token introspection. Finally, they refactored Docker image release workflows with GitHub Actions and Shell scripting, streamlining release processes and improving build consistency.

Oct 1, 2025October 2025: Delivery focus on CI/CD modernization for Docker image releases in apache/hive. Implemented Docker Image Release Workflow Refactor and Standardization to consolidate build logic, standardize Docker image tagging, and improve environment variable preparation for manual and tag-based releases. The changes reduce release time, minimize manual steps, and improve consistency across image builds. Linked commit 434749050102d1f0ea90eb2a88659f47f54bf2ae and tied to HIVE-29261. This work demonstrates strong proficiency in GitHub Actions, Docker, and CI/CD best practices, delivering business value by accelerating releases and reducing risk.

Sep 1, 2025September 2025 monthly summary for apache/hive focusing on security and integration improvements. Implemented OAuth 2.0 authentication for the Iceberg REST Catalog in Hive Metastore, enabling issuer, audience validation and multiple token validation methods (JWT and introspection). Added support for client credentials and principal mapping. Updated components (HMSCatalogAdapter and ServletSecurity) to implement OAuth2 flows and introduced tests for OAuth2 JWT and token introspection validation. This work aligns with security hardening and external identity provider integration.

Aug 1, 2025August 2025 monthly summary for apache/hive focusing on Iceberg integration improvements. Implemented an improvement to IcebergSplit by replacing the custom blockLocations implementation with Iceberg's tested utility org.apache.iceberg.hadoop.Util.blockLocations. This change reduces code duplication, improves maintainability, and aligns IcebergSplit with the Iceberg library, paving the way for easier future updates and more reliable block location handling. Linked to HIVE-29148 and PR #6029 for traceability and review.
