messages in the CheckpointCoordinator
Till Rohrmann created FLINK-5246:
------------------------------------
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}}.
