------------------------------------
Summary: Tasks can fail with PartitionNotFoundException if
consumer deployment takes too long
Key: FLINK-9413
URL: https://issues.apache.org/jira/browse/FLINK-9413
Project: Flink
Issue Type: Bug
Components: Distributed Coordination
Affects Versions: 1.5.0, 1.6.0
Reporter: Till Rohrmann
{{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.
