[ 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.

[ https://issues.apache.org/jira/browse/PIG-240?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Jeff Zhang updated PIG-240: --- Attachment: patch_240.txt This is a init patch for supporting mutilthread pig mode. Pig can submit jobs in each Thread. I found the mOpToCloneMap in LogicalPlanCloneHelper is static shared, so I made some synchronization in this variable. I am not sure whether this patch will completely solve the multithread problem. Because it is not easy to do test multithread program. But at least it works fine for me at least several weeks. So if you are really want to support mulithread, you can try this patch.
