--------------------------------------

[~martijnvisser] We had another incident where we hit this issue and uploaded the full JobManager log: 

Caused by: java.util.concurrent.CompletionException: java.lang.RuntimeException: org.apache.flink.util.FlinkException: Could not retrieve checkpoint 9702 from state handle under checkpointID-0000000000000009702. This indicates that the retrieved state handle is broken. Try cleaning the state handle store.

Please ignore if not related to this issue.
