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.
