Mark Wagner commented on PIG-4036:
----------------------------------
That's the goal of using readOnce. The idea was that the POPackage could be
optimistic/lazy about what bags actually need to be in memory (assume that they
don't need to be), and the classes extending Packager can bring into memory
what it needs. The JoinPackager does not hold the bag in memory and just
iterates over it.
Looking through the other code, it looks like this may be a bug in LitePackager
as well.
