> Add mapPartitionsWithIndex for RDDBarrier
> -----------------------------------------
>
> Key: SPARK-29499
> URL: https://issues.apache.org/jira/browse/SPARK-29499
> Project: Spark
> Issue Type: Bug
> Components: PySpark, Spark Core
> Affects Versions: 2.4.4
> Reporter: Xianyang Liu
> Assignee: Xianyang Liu
> Priority: Major
>
> There is only one method in `RDDBarrier`. We often use the partition index as
> a label for the current partition. We need to get the index from
> `TaskContext` index in the method of `mapPartitions` which is not convenient.
