> Request finished partition state fails due to referential equality comparison
> -----------------------------------------------------------------------------

> Key: FLINK-9406
> URL: https://issues.apache.org/jira/browse/FLINK-9406
> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination
> Affects Versions: 1.5.0, 1.6.0

> The execution of batch jobs can fail because in some cases we cannot retrieve
> the partition state. The problem seems to be that we use referential equality
> in {{JobMaster.java:619}} when requesting the state of a finished result
> partition. This, of course, always fails with a
> {{PartitionProducerDisposedException}} because we should use the proper
> {{equals}} method for the comparison of the {{ResultPartitionID}}.
