-------------------------------------
Summary: Support setting root logger level by config
Key: FLINK-33166
URL: https://issues.apache.org/jira/browse/FLINK-33166
Project: Flink
Issue Type: Improvement
Components: Runtime / Configuration
Reporter: Zhanghao Chen
Users currently cannot change logging level by config and have to modify the
cumbersome logger configuration file manually. We'd better provide a shortcut
and support setting root logger level by config.
There're a number configs already to set logger configurations, like
{{env.log.dir}} for logging dir, {{env.log.max}} for max number of old logging
file to save. We can name the new config {{{}env.log.level{}}}.
