Till Rohrmann created FLINK-9413: ------------------------------------ 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
