That sounds nice. But the lazy evaluation feature of Flink seems to cause the debug process more different with a regular Java/Scala application. Do you know how to debug a Flink application, e.g., tracing some local variables, in IDE?

Hi,

You can run Flink applications locally in your IDE and debug a Flink program just like a regular Java/Scala application.

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.
