Hi Sergey,
Thanks Sergey. Yes I tried that.
I notice
https://nightlies.apache.org/flink/flink-docs-master/docs/concepts/flink-architecture/
which shows the planner running in the Flink application, which in my case is
the SQL client. This makes sense as the debug statements to stdout show in the
sql client console.
I amended the sql-client script to add in extra jvm options including the debug
port. I start the SQL client and can see it starting up the debug port – in my
case 9000.
I go into Intellij which has the Scala plugin and attach to the process – which
I can see. But the Scala breakpoints do not spring. I wonder if it relates to
the planner being loaded in a different class loader.
Kind regards, David.

Hi David
thanks on working on it
May be I don't fully understand your issue however if you are using
IntellijIdea and scala plugin (at least in readme it is mentioned that it
is recommended)
then you should be able to download corresponding sources(at least for
table-planner) set breakpoints both in java and scala and debug...
Or what is the issue with this?
