----------------------------------

             Summary: InputChanelDeploymentDescriptors throws misleading Exception if producer failed/cancelled
                 Key: FLINK-5275
                 URL: https://issues.apache.org/jira/browse/FLINK-5275
             Project: Flink
          Issue Type: Bug
          Components: Network
            Reporter: Ufuk Celebi
            Assignee: Ufuk Celebi


Reported by [~rmetzger]. While creating the input channel deployment descriptors for a job that does not allow lazy deployment (all streaming jobs), Robert got an {{ExecutionGraphException}} with the message {{Trying to eagerly schedule a task whose inputs are not ready}} in the {{InputChannelDeploymentDescriptor}}.

This was not reported as the root cause and is most likely due to a failed producer. For such cases, it makes sense to include the execution state of the producing task so that users see that this is related to the producer.
