> Make `RDDBarrier.mapParititions` similar to `RDD.mapPartitions`
> ---------------------------------------------------------------
>
> Key: SPARK-25045
> URL: https://issues.apache.org/jira/browse/SPARK-25045
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.4.0
> Reporter: Jiang Xingbo
> Priority: Major
>
> Signature of the function passed to `RDDBarrier.mapPartitions()` is different
> from that of `RDD.mapPartitions`. The latter doesn’t take a TaskContext. We
> shall make the function signature the same to avoid confusion and misusage.
