> Currently there are two place where we construct the hash expression based on the partition
fields:
> 1. InsertLocalExchangeVistor (generates RexExpr type)
> 2. PRelUtil.getHashExpression (generate LogicalExpression type)
> Having this logic in two places makes them prone to errors and they can easily go out
of sync causing hard to debug verification failures.
