----------------------------------------------------------------
Is it possible to backport this to 1.2? It fixes 2 annoying issues:
(1) If you do:
cache table foo as ....;
cache table foo;
The second cache table creates a 2nd, new RDD, meaning the first cached RDD is
stuck in-memory and can't be deleted ("uncache foo" just deletes the 2nd RDD,
but the 1st one is still there)
(2)
cache table foo as ...;
drop table foo;
Leaves foo still in-memory (and, similar to the above, now un-deletable).
