> Key: BEAM-9161
> URL: https://issues.apache.org/jira/browse/BEAM-9161
> Project: Beam
> Issue Type: Bug
> Components: runner-flink
> Reporter: Maximilian Michels
> Assignee: Maximilian Michels
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> The issue results in exceptions like "Already closed" due to a concurrent
> close of the remote input receivers from (1) the main thread and (2) the
> thread for finishing the bundle. In combination with the
> {{bundleFinishedCallback}} it may have also caused a slowdown due to closing
> a bundle when it was not needed.
> We should make sure that only one thread at a time can start or finish a
> bundle.
