Yes, I would say that we tackle this problem after we have removed the
legacy code. For the moment, there is a work around to set the max backoff time
higher for the data connections.

> 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.
