[ https://issues.apache.org/jira/browse/PIG-761?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Daniel Dai updated PIG-761: --- Attachment: PIG-761-1.patch The problem lies in the complexity between limit and one of the optimization. More specific, optimization POPackageAnnotator search for matching POLocalRearrange in the map plan, if not, search in the predecessor's reduce plan. However, if we have a limit, limit will introduce a map-reduce job between the original map-reduce job and its predecessor. POPackageAnnotator cannot find the POLocalRearrange then. To fix it, we mark the map reduce job introduced by limit, and in POPackageAnnotator, if we saw a limit map reduce job, we will search POLocalRearrange in limit job's parent.
