Aaron Staple commented on SPARK-546:
------------------------------------
Hi, I think there are two features requested in this ticket:
1) full outer join
2) an RDD function to join >2 rdds in a single shuffle (e.g. multiJoin function)
I’ve implemented #1 in my recent PR, but not #2. I’m happy to implement #2 as
well though.
Would it make sense to reopen this ticket? File a new ticket?

> Also it'd be nice to provide a way for users to join multiple RDDs on the
> same key in a single shuffle.
