--------------------------
Resolution: Won't Fix
> Add a groupByKey which returns a special GroupBy object like in pandas
> ----------------------------------------------------------------------
>
> Key: SPARK-3312
> URL: https://issues.apache.org/jira/browse/SPARK-3312
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: holdenk
> Priority: Minor
>
> A common pattern which causes problems for new Spark users is using
> groupByKey followed by a reduce. I'd like to make a special version of
> groupByKey which returns a groupBy object (like the Panda's groupby object).
> The resulting class would have a number of functions (min,max, stats, reduce)
> which could all be implemented efficiently.
