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

Hi
I’m wondering if new debugging methods/tools are urgent for Flink
development. I know there already exists some debug methods for Flink,
e.g., remote debugging of flink
clusters(https://cwiki.apache.org/confluence/display/FLINK/Remote+Debugging+of+Flink+Clusters).
But are they are convenient enough?
Best regards.
