Chesnay Schepler commented on FLINK-3057:
-----------------------------------------

Sure. Right now, the python process that generates the plan can only send 
information to the java side; there exists no mechanism to send data the other 
way. This means that several features can't be supported, like the 
JobExecutionResult, createProgramPlan() or collect().

The PR I'm planning will provide a rudimentary way to send data back, along 
with a proof-of-concept implementation of the JobExecutionResult (you can 
access the netRuntime).
