[PIG-1603|https://issues.apache.org/jira/browse/PIG-1603] is trying to solve the problem by adding a LOScalar operator. Here is a different approach. We will add a soft link to the plan, and soft link is only visible to the walkers. All other part of the logical plan does not know the existence of the soft link. The benefits are: 1. Logical plan do not need to deal with LOScalar, this makes logical plan cleaner 2. Conceptually scalar dependency is different. Regular link represent a data flow in pipeline. In scalar, the dependency means an operator depends on a file generated by the other operator. It's different type of data dependency. 3. Soft link can solve other dependency problem in the future. If we introduce another UDF dependent on a file generated by another operator, we can use this mechanism to solve it. Currently, there are two cases we can use soft link: 1. scalar dependency, where ReadScalar UDF will use a file generate by a LOStore 2. store-load dependency, where we will load a file which is generated by a store in the same script. This happens in multi-store case. Currently we solve it by regular link.

[jira] Commented: (PIG-1606) flatten documentation does not discuss flatten of empty bag
[
https://issues.apache.org/jira/browse/PIG-1606?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12908259#action_12908259

Alan Gates commented on PIG-1606:
-
flatten of an empty bag has to be a black hole else cogroup + foreach != inner
join, which we claim it does.

> From the existing flatten documentation, it is not clear that flatten of an
> empty bag results in that row being discarded .
> For example the following query gives no output -
> {code}
> grunt> cat /tmp/empty.bag
> {} 1
> grunt> l = load '/tmp/empty.bag' as (b : bag{}, i : int);
> grunt> f = foreach l generate flatten(b), i;
> grunt> dump f;
> grunt>
> {code}
