Worked on stabilizing the Task API for Apache DolphinScheduler, focusing on execution reliability in resource-constrained environments. Addressed a bug where the shell’s absolute path was missing from bootstrap commands in resource-limited mode, which previously caused execution failures. The solution involved updating backend Java logic and shell scripting to ensure the correct path was always included. To validate the fix, comprehensive unit tests were added to cover bootstrap command generation across all execution modes. This targeted change improved the robustness of task execution in the repository, demonstrating a methodical approach to backend development, shell scripting, and automated testing within a complex system.
