Stephan Ewen commented on FLINK-18894:
--------------------------------------
I think that StateFun has no way of handling finite input at the moment. Be
that a bounded input, or stopping an unbounded input.
The common mechanism in Flink doesn't work because of the loop.
> StateFun job stalls on stop-with-savepoint
> ------------------------------------------
>
> Key: FLINK-18894
> URL: https://issues.apache.org/jira/browse/FLINK-18894
> Project: Flink
> Issue Type: Bug
> Affects Versions: statefun-2.1.0, statefun-2.2.0
> Reporter: Seth Wiesman
> Priority: Blocker
>
> Stateful Function jobs stall when performing a stop with savepoint. The
> FunctionDispatchOperator never acknowledges completion and so the savepoint
> never finishes. Taking a savpoint and then canceling in two seperate steps
> works correctly, it is only the stop command that has issues.
> {code}
> curl -X POST localhost:8001/jobs/:jobid/stop -d '{"drain": false}'
> {code}
