Stefan Richter commented on FLINK-6633:
---------------------------------------
[[email protected]], I think this log was already enough to figure out the
problem. Good news is, the basic incremental checkpointing works as expected.
Bad news is the combination of {{StandaloneCompletedCheckpointStore}} and
externalized checkpoints is broken. {{StandaloneCompletedCheckpointStore}} does
not recover completed checkpoints on restore and therefore does not re-register
them. The fix will first add the checkpoint from which we restored to the
{{StandaloneCompletedCheckpointStore}}, so that it can be registered as shared
state again, and references from future checkpoints work.
> Register with shared state registry before adding to CompletedCheckpointStore

> Introducing placeholders for previously existing shared state requires a
> change that shared state is first registering with {{SharedStateregistry}}
> (thereby being consolidated) and only after that added to a
> {{CompletedCheckpointStore}}, so that the consolidated checkpoint is written
> to stable storage.
