ASF GitHub Bot commented on FLINK-9413: --------------------------------------- Github user RalphSu commented on the issue: https://github.com/apache/flink/pull/6103 @zhangminglei does the description of this issue indicate a workaround for this? I'm using 1.4.2. With dozens of jobs been submitted to my cluster, i'm constantly see this PartitionNotFound exception. > 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: 1.4.0, 1.5.0, 1.6.0 > Reporter: Till Rohrmann > Assignee: zhangminglei > Priority: Critical > Labels: pull-request-available > > {{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)
