Robert Metzger commented on FLINK-2081:
---------------------------------------
You can always work around that by leaving the open method empty and initialize
your stuff on the first next()/hasNext() call.
> Change order of restore state and open for Streaming Operators

> Key: FLINK-2081
> URL: https://issues.apache.org/jira/browse/FLINK-2081
> Project: Flink
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 0.9
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek

> Right now, the order is restore state -> open. Users often set internal state
> in the open method, this would overwrite state that was restored from a
> checkpoint. If we change the order to open -> restore this should not be a
> problem anymore.
