> Pig tries to determine which fields in a query script file will be needed and passes
that information to the load function, thereby optimizing the query by reducing the data to
be loaded.
> To support this optimization, Zebra needs to implement fieldsToRead method in TableLoader
class to utilize this information. This jira is for this new feature.
> For more information of this optimization on pig side, one can refer to jira:  PIG-653
