> Key: FLINK-9413
> URL: https://issues.apache.org/jira/browse/FLINK-9413
> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination
> Affects Versions: 1.4.0, 1.5.0, 1.6.0
> Reporter: Till Rohrmann
> Assignee: mingleizhang
> Priority: Critical
>
> {{Tasks}} can fail with a {{PartitionNotFoundException}} if the deployment of the producer takes too long. More specifically, if it takes longer than the {{taskmanager.network.request-backoff.max}}, then the {{Task}} will give up and fail.
> The problem is that we calculate the {{InputGateDeploymentDescriptor}} for a consuming task once the producer has been assigned a slot but we do not wait until it is actually running. The problem should be fixed if we wait until the task is in state {{RUNNING}} before assigning the result partition to the consumer.
