    okey...
    
    I encounter issue when submit jobs, stack as below, looks the same with this one. Is this a regression, or are we thinking the fix will break existing code?

> {{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.
