    This needs a descriptive Javadoc.

>             Project: Flink
>          Issue Type: Bug
>          Components: Kinesis Connector
>    Affects Versions: 1.4.0, 1.3.2, 1.5.0
>            Reporter: Thomas Weise
>            Assignee: Thomas Weise
>            Priority: Major
>
> The hash code of the shard is used to distribute discovered shards over 
> subtasks round robin. This works as long as shard identifiers are sequential. 
> After shards are rebalanced in Kinesis, that may no longer be the case and 
> the distribution become skewed.
