Koji Noguchi commented on PIG-5338: ----------------------------------- Thanks [~gphillips] for the report! Please let us know if you want to work on the fix yourself or would leave the fix to others. > Prevent deep copy of DataBag into Jython List > --------------------------------------------- > > Key: PIG-5338 > URL: https://issues.apache.org/jira/browse/PIG-5338 > Project: Pig > Issue Type: Improvement > Reporter: Greg Phillips > Priority: Major > > Pig Python UDFs currently perform deep copies on Bags converting them into > Jython PyLists. This can cause Jython UDFs to run out of memory and fail. A > Jython DataBag which extends PyList could allow for iterative access to > DataBag elements, while only performing a deep copy when necessary. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
