> POPackage uses DefaultDataBag during reduce process to hold data. It is
> registered with SpillableMemoryManager and prone to OutOfMemoryException.
> It's better to pro-actively managers the usage of the memory. The bag fills
> in memory to a specified amount, and dump the rest the disk. The amount of
> memory to hold tuples is configurable. This can avoid out of memory error.
