Subject Re: remote debugging

Hey Stefano!

I think that question is bound to come up again. I created a page in the
Flink Wiki to document this.

If you have a few moments, would be great if you could add your description
there:
https://cwiki.apache.org/confluence/display/FLINK/Remote+Debugging+of+Flink+Clusters
(it is linked from the front page
https://cwiki.apache.org/confluence/display/FLINK/Apache+Flink+Home )

Greetings,
Stephan
