### What changes were proposed in this pull request? Add mapPartitionsWithIndex for RDDBarrier. ### Why are the changes needed? 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. ### Does this PR introduce any user-facing change? No ### How was this patch tested? New UT. Closes #26148 from ConeyLiu/barrier-index. Authored-by: Xianyang Liu <xianyang.liu@intel.com> Signed-off-by: Xingbo Jiang <xingbo.jiang@databricks.com> |
