Is this a known issue. We do a stop + savepoint with drain. I see no back pressure on our operators. It essentially takes a SP and then the SInk ( StreamingFileSink to S3 ) just stays in the RUNNING state.
Without drain i stop + savepoint works fine. I would imagine drain is important ( flush the buffers etc ) but why this hang ( I did it 3 times and waited 15 minutes each time ). Regards.
