                 Key: PIG-1000
                 URL: https://issues.apache.org/jira/browse/PIG-1000
             Project: Pig
          Issue Type: Improvement
    Affects Versions: 0.4.0
            Reporter: Ying He
            Assignee: Ying He
             Fix For: 0.6.0


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.
