    Resolution: Won't Fix

I don't see this feature being particularly popular, especially since its 
relatively easy to implement outside of Spark its self. If you disagree feel 
free to re-open this.

> Add takeOrderedByKey function to extract top N records within each group

>                 Key: SPARK-10223
>                 URL: https://issues.apache.org/jira/browse/SPARK-10223
>             Project: Spark
>          Issue Type: New Feature
>          Components: PySpark
>            Reporter: Ritesh Agrawal
>            Priority: Minor
> Currently PySpark has takeOrdered function that returns top N records. 
> However often you want to extract top N records within each group. This can 
> be easily implemented using combineByKey operation and using fixed size heap 
> to capture top N within each group. A working solution can be found over 
> [here](https://ragrawal.wordpress.com/2015/08/25/pyspark-top-n-records-in-each-group/)
