Kakao Open-Sources 'CMUX', a CLI Tool for Hadoop Cluster Management

Kakao has open-sourced 'CMUX', an interactive command-line interface tool for managing Hadoop clusters based on Cloudera Manager. CMUX provides a four-stage workflow: it ingests data via the Cloudera Manager REST API, performs search and filtering using FZF, generates commands with Ruby code, and executes them in parallel using TMUX. After stabilizing the tool through approximately one year of internal use, Kakao has published it on GitHub to help developers improve their CLI productivity.
