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 On Tue, May 17, 2016 at 4:26 AM, Vijay Srinivasaraghavan < vijikar...@yahoo.com.invalid> wrote: > Awesome, thanks Stefano!! > > On Monday, May 16, 2016 9:57 AM, Stefano Baghino < > stefano.bagh...@radicalbit.io> wrote: > > > I had to do it a couple of times.
