[jira] Updated: (PIG-240) Support launching concurrent Pig jobs
from one VM
[ https://issues.apache.org/jira/browse/PIG-240?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bennie Schut updated PIG-240:
-----------------------------
Attachment: pig-240-1.patch
I was also getting multithreading issues like "Unable to find clone for op Const 16-169"
the previous patch didn't help in my case (not sure why) however I changed the LogicalPlanCloneHelper to be used in a non-static way.
However I have to admit that I'm not 100% clear on how this LogicalPlanCloneHelper is working in the big picture.
This however completely solved my problem.

> For some applications it would be convenient to launch concurrent Pig jobs from a single VM. This is currently not possible since Pig has static mutable state.
