(was: 1.1.0)
> Fix documentation about determinism of KeySelectors
> ---------------------------------------------------
>
> Key: FLINK-4047
> URL: https://issues.apache.org/jira/browse/FLINK-4047
> Project: Flink
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 1.1.0, 1.0.3
> Reporter: Fabian Hueske
> Labels: starter
>
> KeySelectors must return deterministic keys, i.e., if invoked multiple times on the same object, the returned key must be the same.
> The documentation about this aspect is broken ("The key can be of any type and be derived from arbitrary computations.").
> We need to fix the JavaDocs of the {{KeySelector}} interface and the web documentation (https://ci.apache.org/projects/flink/flink-docs-master/apis/common/index.html#specifying-keys).
