May 2025 monthly summary for pentaho/pentaho-hadoop-shims: Focused on security, compatibility, and maintainability through targeted dependency upgrades across core Hadoop shim components. Delivered two upgrade streams with corresponding build configuration updates, validated impact on the build surface, and prepared the repository for upcoming features that rely on newer libraries. No major defects reported this month; changes reduce security risk and align with latest ecosystem releases.

Monthly summary for 2025-04: Focused on upgrading Libthrift to 0.20.0 across pentaho/pentaho-hadoop-shims (apachevanilla, EMR700, dataproc). This work improves compatibility with modern Hadoop ecosystems, applies security patches, and reduces maintenance risk across shims. Highlights include cross-repo coordination, a single commit PPP-5699, and readiness for future updates.

February 2025: Delivered a critical compatibility fix for the libthrift upgrade in pentaho/big-data-plugin. Resolved missing/incorrect libthrift dependencies to ensure compatibility, prevent runtime errors, and maintain system stability. This work reduces risk in production by stabilizing the runtime environment after library upgrades.

Monthly work summary for 2025-01 focusing on the pentaho/pentaho-scheduler-plugin improvements. This period highlights a critical bug fix addressing timezone-related date display in the scheduler UI and an accompanying refactor to improve date handling, traceability, and maintainability within the repository.

December 2024 monthly summary for Pentaho development. Delivered centralized server-side control of internal variable visibility across Pentaho Platform and Scheduler Plugin, simplifying client-side APIs and configuration. Restored visibility and editability of internal variables in PUC and Kettle components, and stabilized the scheduler parameter preview experience. Implemented server-side scheduler configuration via a new server properties approach, refactoring SchedulerHelper and SchedulerResourceUtil to read properties from the server. Added a copyright header to SchedulerHelper.java to ensure licensing compliance. Performed targeted API/UI rollbacks to revert unintended changes from BISERVER-15051 and BISERVER-15176 where applicable, restoring stable functionality. Overall, these changes reduce configuration drift, improve consistency across UIs, and enhance developer productivity while maintaining licensing compliance.

November 2024: Delivered a security-focused dependency upgrade in pentaho/pentaho-hadoop-shims by upgrading the Commons-Config library to address known vulnerabilities. The change is a minimal, straightforward dependency update (commit e72c1fa883c36909d6dc3e0d2f8289d8fc3e7c8f) with no API changes. This reduces vulnerability exposure, preserves existing behavior, and maintains compatibility with downstream modules. The work demonstrates strong patch governance, dependency management, and regression testing in a Java/Maven-based stack, reinforcing security posture and maintainability for the Hadoop shims.
