Re: Data sink finishes before previous task finishes

Hi Regina,

from the top of my hat, I cannot tell why an intermediate operator stays in state running while all others transitioned to a terminal state. Could you share the logs with us? They might be helpful in understanding the problem better.

I don't know why this should happen. AFAIK, operators should transition to the finished state after their input operator finished.
Canceling in case of a failure is a different thing, but obviously not the case here.

This might be a bug.
@Till, do you know what might cause such behavior in Flink 1.2.x?

Best, Fabian

I’m still using Flink 1.2.1 on some production streams and I’m seeing this weird behavior where I’m seeing the flatMap stay in running while the data sink is in finished state. What’s causing this behavior?
