> Currently, Hive does not allow altering partition column types. As we've
> discouraged users from using non-string partition column types, this presents
> a problem for users who want to change there partition columns to be strings,
> they have to rename their table, create a new table, and copy all the data
> over.
> To support this via the CLI, adding a command like ALTER TABLE <table_name>
> PARTITION COLUMN (<column_name> <new type>);
