[jira] [Resolved] (SPARK-10296) add preservesParitioning parameter to RDD.map

     [ https://issues.apache.org/jira/browse/SPARK-10296?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Josh Rosen resolved SPARK-10296.
--------------------------------
    Resolution: Won't Fix

Given the limited interest in this feature, combined with the fact that this is easily achievable via mapPartitions, the additional API complexity, code review time, and compatibility concerns don't seem well-justified to me. Therefore, I'm going to mark this as "Won't fix" for now. If anyone strongly disagrees, we can re-open.

> It would be nice to add the Boolean parameter preservesParitioning with default false to RDD.map method just as it is in RDD.mapPartitions method.
> If you agree I can submit a pull request with this enhancement.
