> ALTER TABLE CHANGE COLUMN is allowed for tables, but not for partitions. Same for add/replace
> Allowing this for partitions can be useful in some cases. For example, one user has tables
with Hive 0.12 Decimal columns, which do not specify precision/scale. To be able to properly
read the decimal values from the existing partitions, the column types in the partitions need
to be changed to decimal types with precision/scale.
