### PR description This PR introduces a new developer utility script, `dev/update_interpreter.sh`, that automates the full interpreter rebuild and restart workflow during Apache Zeppelin interpreter development. The script replaces a long, error-prone manual process with a single command: `./dev/update_interpreter.sh <interpreter-name> ` ### Problem When developing or modifying Zeppelin interpreters, developers currently need to manually execute multiple commands in the correct order to see changes take effect: - Build the interpreter module - Copy the generated JAR to the interpreter directory (frequently forgotten) - Copy interpreter-setting.json - Stop Zeppelin - Clear interpreter cache - Clean local repository - Restart Zeppelin This workflow is: Error-prone -> missing the JAR copy step leads to silent failures Time-consuming -> repeated execution of 7+ commands slows iteration Inconsistent –> cleanup steps vary between developers Hard to debug –> no validation, logging, or clear failure feedback ### Solution This PR adds `dev/update_interpreter.sh`, which automates the entire workflow with built-in validation, logging, and safety checks. #### Key features: **One-command workflow** `./dev/update_interpreter.sh <interpreter-name> ` **Safety & validation** - Verifies interpreter module exists - Confirms JAR build success before copying - Validates Zeppelin server build before restart - Verifies Zeppelin startup status (does not silently fail) - Improved developer experience - Clear success/failure indicators **Timestamped logs** `update_interpreter_<name>_<timestamp>.log ` - Automatically displays Zeppelin logs on startup failure - Edge-case handling - Can be run from any directory - Auto-detects Zeppelin project root - Automatically surfaces relevant logs when failures occur -- This is an automated message from the Apache Git Service.
