> 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.)
