[jira] [Resolved] (SPARK-3626) Replace AsyncRDDActions with a more general async. API

Josh Rosen resolved SPARK-3626.
-------------------------------
    Resolution: Won't Fix

I'm closing this as "Won't Fix" for now.  The more general API (as described in my PR) has some confusing semantics RE: cancellation and may be more general than what most users want / need.

> The experimental AsyncRDDActions APIs seem to only exist in order to enable job cancellation.
> We've been considering extending these APIs to support progress monitoring, but this would require stabilizing them so they're no longer {{@Experimental}}.
> Instead, I propose to replace all of the AsyncRDDActions with a mechanism based on job groups which allows arbitrary computations to be run in job groups and supports cancellation / monitoring of Spark jobs launched from those computations.
> (full design pending; see my GitHub PR for more details).
