Yes, I have written this above (that's why I replaced it with one using the
partitioned states). But that's not the only problem. If you introduce a
shuffle between two maps (.shuffle()) then those are not correctly checkpointed
either.

> Partitioned states are currently stored per-key in statehandles. This is
> alright for in-memory storage but is very inefficient for HDFS.
> The logic behind the current mechanism is that this approach provides a way
> to repartition a state without fetching the data from the external storage
> and only manipulating handles.
> We should come up with a solution that can achieve both.
