Local engine loses records in splits

                 Key: PIG-849
                 URL: https://issues.apache.org/jira/browse/PIG-849
             Project: Pig
          Issue Type: Bug
            Reporter: Gunther Hagleitner
         Attachments: local_engine.patch

When there is a split in the physical plan records can be dropped in certain circumstances.

The local split operator puts all records in a databag and turns over iterators to the POSplitOutput
operators. The problem is that the local split also adds STATUS_NULL records to the bag. That
will cause the databag's iterator to prematurely return false on the hasNext call (so a STATUS_NULL
becomes a STATUS_EOP in the split output operators).
