> The {{ZooKeeperCompletedCheckpointStore}} reads a set of
> {{RetrievableStateHandles}} from ZooKeeper upon recovery. It then tries to
> retrieve the {{CompletedCheckpoint}} from the latest state handle. If the
> retrieve operation fails, then the whole recovery of completed checkpoints
> fails even though the store might have read older state handles from
> ZooKeeper.
> I propose to harden the behaviour by removing broken state handles and
> returning the first successfully retrieved {{CompletedCheckpoint}}.
