Description

(Some) Ozone CLI commands log to ozone-shell.log instead of the console. The goal was to reduce output clutter, but it causes problems due to file ownership.

Other Ozone commands use a log config inherited from Hadoop, which allows customising root logger and default log level via environment variables OZONE_ROOT_LOGGER and OZONE_LOGLEVEL.

The goal of this task is to get rid of the custom config for CLI, scrap ozone-shell.log, and respect these environment variables. CLI commands should disable logging by default.
