Yes, but not something that provides both the partition index AND the input
split. Moreover, HadoopPartition is private since 2.0.

> Add function mapPartitionsWithInputSplitAndIndex to NewHadoopRDD
> ----------------------------------------------------------------
>
> Key: SPARK-32716
> URL: https://issues.apache.org/jira/browse/SPARK-32716
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 3.0.0
> Reporter: Patrick Grandjean
> Priority: Major
>
> This is a proposal to add the following function to NewHadoopRDD:
> {code:java}
> def mapPartitionsWithInputSplitAndIndex[U: ClassTag](
> f: (InputSplit, Int, Iterator[(K, V)]) => Iterator[U],
> preservesPartitioning: Boolean = false
> ): RDD[U]
> {code}
> This new function would provide the input split with its partition index.
> Having the partition index may be useful when trying to determine the mapping
> between part-XXXXX files and input splits.
