> Add metadata in MapStatus to support custom shuffle manager
> -----------------------------------------------------------
>
> Key: SPARK-33114
> URL: https://issues.apache.org/jira/browse/SPARK-33114
> Project: Spark
> Issue Type: Improvement
> Components: Shuffle
> Affects Versions: 3.0.1
> Reporter: BoYang
> Assignee: Apache Spark
> Priority: Major
>
> Current MapStatus class is tightly bound with local (sort merge) shuffle which uses BlockManagerId to store the shuffle data location. It could not support other custom shuffle manager implementation.
> We could add "metadata" to MapStatus and allow different shuffle manager implementation to store information related to them.
