> Make Queryable State Key-Group Aware

>                 Key: FLINK-4556
>                 URL: https://issues.apache.org/jira/browse/FLINK-4556
>             Project: Flink
>          Issue Type: Bug
>          Components: Streaming
>    Affects Versions: 1.2.0
>            Reporter: Aljoscha Krettek
>            Assignee: Stefan Richter
>            Priority: Blocker
> The recent introduction of key-grouped state breaks queryable state because 
> the JobManager does not yet forward the client to the correct TaskManager 
> based on key-group ranges.
> This will either have to be implemented on the JobManager side, i.e. in 
> {{AkkaKvStateLocationLookupService}} or on the {{TaskManager}} when state is 
> registered. The JobManager can know the mapping because it should know the 
> {{parallelism}}/{{maxParallelism}} which it can use to determine where the 
> state for a key-group is stored. The {{TaskManager}} send a 
> {{NotifyKvStateRegistered}} message that already contains a {{keyGroupIndex}} 
> field that is not useful/correct at the moment, though.
