> Project: Flink
> Issue Type: Bug
> Components: Distributed Runtime
> Reporter: Ufuk Celebi

>
> The savepoint coordinator requires that the number of collected states of an
> operator and the parallelism of the new job (the one to be restored) match
> exactly. This is too strict.
> For example a Kafka source with parallelism 2 and a single Kafka partition
> does not collect state for one of the two sources (hence it is not part of
> the savepoint state). Currently, restoring the same job with the same
> parallelism fails, which should not happen.
