> SPARK-48413 has brought ability to change collation on table.
> But it seems to be too wide, because people couldn't change the whole
> StructType/MapType/ArrayType by altering before.
> Right now there is found problem with altering collation when table has
> metadata. Altering will be failed because of a metadata mismatch between
> user's type (that doesn't have metadata) and existing schema.
> So I suggest to shrink the feature to only leaf string types.
> People will be able to change any collation still, but they need to use full
> column path:
> {code:sql}
> ALTER TABLE table ALTER COLUMN full.column.path TYPE STRING COLLATE UNICODE
> {code}
