Hi,

Our most useful tool when debugging Flink is actually the simple log
files, because debugger just slow things down too much for us.

However, having to re-deploy the entire cluster to change the logging
level is a pain (we use YARN),

so we would really like an easier method to change the logging level at
runtime.


Regards,

Kien
