Jason Dere commented on HIVE-12320:
-----------------------------------
I think this looks ok. One thing I will note is that it is possible to change a
table column from short to decimal, but if you then try to change it back from
decimal these rules will kick in and complain because decimal is not implicitly
convertible to short. So this would require the user to set
hive.metastore.disallow.incompatible.col.type.changes=false before doing this.
> hive.metastore.disallow.incompatible.col.type.changes should be true by
> default
