------------------------------
Resolution: Invalid
> Extend state handle provider interface to list all state handles
> ----------------------------------------------------------------
>
> Key: FLINK-2513
> URL: https://issues.apache.org/jira/browse/FLINK-2513
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Runtime
> Reporter: Ufuk Celebi
>
> This is a follow up issue to FLINK-2354.
> In FLINK-2354 we use ZooKeeper to persist state handles. In certain failure
> scenarios, there can be lingering state handles, which have not been written
> to ZooKeeper, but which were already created.
> These can be cleaned up on startup, if the state handle provider
> implementation kept track of their state handles. With the current
> implementations it would be possible, e.g. list the directory (file system)
> of no state is persistent (job manager).
> It would be fair enough have this as an optional operation.
