when writing column mapping like: (k1, k1=funcA(k1), k2=funcB(k1)) The expected rewriting is: (k1, k1=funcA(k1), k2=funcB(funcA(k1))) But when doing the substitution, it may encounter self referencing problem. When replacing `k1` in `k2=funcB(k1)` with `funcA(k1)`, the `k1` in `funcA(k1)` is also referencing to `funcA(k1)`. -- This is an automated message from the Apache Git Service.
