Thejas M Nair updated PIG-1603:
-------------------------------
Attachment: PIG-1603.1.patch
PIG-1603.1.patch
Patch adds a new Logical operator LOScalar . A LogicalOperator that is using a
relation (say X) as scalar in its inner plan will have a LOScalar added as a
predecessor which also have the relation X as a predecessor. Visitors have been
changed to handle this new logical operator.
The test case TestFRJoin2.testConcatenateJobForScalar3 has been enabled.

>
> The LogicalOperator that has a ReadScalar udf has a dependency on the
> relation that is provides the input to scalar variables. But this is not
> captured in the graph representation, and as a result DependencyOrderWalker
> does not traverse the graph in the real dependency order.
> The testcase TestFRJoin2.testConcatenateJobForScalar3 fails as a result of
> this issue. (It has been commented out for now.)
