Description

relevant https://issues.apache.org/jira/browse/FLINK-33166

When I set env. log. level=DEBUG and start the flink job by yarn application mode, the logs of TM and JM are still INFO.

Preliminary inference is that it is ROOT_ LOG_ LEVEL value transmission link is not complete enough.

So I used the following configuration:

containerized. taskmanager. env. ROOT_ LOG_ LEVEL=DEBUG

containerized. master. env. ROOT_ LOG_ LEVEL=DEBUG

 

When starting the job by yarn application mode, TM and JM can output DEBUG level logs.

 

Repair ideas:

Fill the value of env. log. level into the Flink configuration by containerized. xxx. env. ROOT_ LOG_ LEVEL before obtaining the environment variable for the container
