> For a RS of a join operator, if the join key corresponding to this RS does not appear
in the SELECT clause, ColumnPruner will drop the entry of this column in colExprMap. 
> Example:
> {code}
> SELECT x.key FROM src1 x JOIN src y ON (x.key = y.key);
> {\code}
> Before CP,
> {code}
> colExprMap of RS corresponding to x: {VALUE._col3=Column[INPUT__FILE__NAME], VALUE._col2=Column[BLOCK__OFFSET__INSIDE__FILE],
VALUE._col1=Column[value], VALUE._col0=Column[key]};
> colExprMap of RS corresponding to y: {VALUE._col3=Column[INPUT__FILE__NAME], VALUE._col2=Column[BLOCK__OFFSET__INSIDE__FILE],
VALUE._col1=Column[value], VALUE._col0=Column[key]}.
> {\code}
> After CP,
> {code}
> colExprMap of RS corresponding to x: {VALUE._col0=Column[key]};
> colExprMap of RS corresponding to y: {}.
> {\code}
