> 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>);
