> Local engine loses records in splits

> 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).
