-----------------------------------
Summary: Support configurable log level
Key: FLINK-20735
URL: https://issues.apache.org/jira/browse/FLINK-20735
Project: Flink
Issue Type: Improvement
Affects Versions: 1.12.0
Reporter: zlzhang0122
Fix For: 1.13.0
Now the default log level of flink is "INFO" and if we want to change the
default log level, we have to change that in many log file and this may affect
all the jobs using these config, I think we can expose a log level config for
users to change the default log level for every single job.And if users don't
provide the config value, the default log level won't be changed.
