> * Implement _PartitionShuffleDescriptor_ for covering necessary abstract info.
>  * Implement _ShuffleDeploymentDecriptor_ generated from _PartitionShuffleDecriptor_.
>  * Define _ShuffleMaster_ interface and create a simple implementation on JM side which relies on currently implemented NetworkEnviroment on TM side.
>  * Define _ShuffleManager_ interface for creating ShuffleMaster.
>  * Introduce a Flink configuration option for _ShuffleManager_ implementation. Default value for it could be <none> which serves as a feature flag at the moment to use current code paths.
