> 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}}.
