------------------------------------
Summary: 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
Reporter: Till Rohrmann
Assignee: Nico Kruber
Fix For: 1.5.0
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}}.
