> In Calcite v1.37, we use coercenodes to change smaller datatypes to match Impala types. For instance, the numeric '1' needs to be a tinyint in Impala, whereas Calcite makes it an int (CALCITE-7120 is filed for this problem).
> On upgrade from Calcite 1.37 to Calcite 1.40, the mechanism in coercenodes fails because of work Calcite did in the AST portion of their code.  So we need to come up with another way to do this.
