Arvid Heise commented on FLINK-19864:
-------------------------------------
I wouldn't like to change production code to get deprecated test code working.
I could assign the ticket nonetheless and you could try out if it's working and
maybe check if there are alternatives that don't need changes to the production
code.
Another option could be to check the StreamStatus/InputStatus for detecting
that all input has been processed and remove this thread status fiddling
altogether.
