Nemo Chen commented on YARN-5506:
---------------------------------
That's a good point. If the level were changed to DEBUG in this code, I guess
the logs won't be printed under the following condition:
- the user includes the "debug" option,
- but with the logging level config set to be "INFO".
But is this a normal/expected scenario?
