interleave partitions?

2014-03-26 Thread Walrus theCat 
Hi,

I want to do something like this:

rdd3 = rdd1.coalesce(N).partitions.zip(rdd2.coalesce(N).partitions)

I realize the above will get me something like Array[(partition,partition)].

I hope you see what I'm going for here -- any tips on how to accomplish
this?

Thanks

Answering my own question here.  This may not be efficient, but this is
what I came up with:

rdd1.coalesce(N).glom.zip(rdd2.coalesce(N).glom).map { case(x,y) = x++y}
