Please add another test with composite partition keys
(`.partitionByRange(0,2)`).
> [GitHub] Enable Range Partitioner
> ---------------------------------
>
> Key: FLINK-7
> URL: https://issues.apache.org/jira/browse/FLINK-7
> Project: Flink
> Issue Type: Sub-task
> Components: Distributed Runtime
> Reporter: GitHub Import
> Assignee: Chengxiang Li
> Fix For: pre-apache
>
>
> The range partitioner is currently disabled. We need to implement the
> following aspects:
> 1) Distribution information, if available, must be propagated back together
> with the ordering property.
> 2) A generic bucket lookup structure (currently specific to PactRecord).
> Tests to re-enable after fixing this issue:
> - TeraSortITCase
> - GlobalSortingITCase
> - GlobalSortingMixedOrderITCase
