@tillrohrmann already did that, it looks alleviate though not fix. I'm
upgrade from 1.2.0 to 1.4.2. Major thing i can see is TM now connection to HDFS
instead of only talk to JobManager, could this increase the possibility of
this issue?

> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination

> {{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.
