------------------------------------
Summary: Don't discard unknown checkpoint messages in the
CheckpointCoordinator
Key: FLINK-5246
URL: https://issues.apache.org/jira/browse/FLINK-5246
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Affects Versions: 1.1.4
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.1.4
The delicate interplay of the {{CheckpointCoordinator}} and the
{{SavepointCoordinator}} requires that unknown checkpoint messages are not
discarded but given to the other coordinator. If both coordinator don't accept
the checkpoint message, then the associated state will be discarded by the
{{JobManager}}.
