> Since HIVE-28909, we change the MColumnDescriptor's identity-type to
> application from datastore in the package.jdo. It makes the
> getDataStoreId(MColumnDescriptor.class) throw the MetaException, as this
> IdentityType is no longer the IdentityType.DATASTORE any more, then the
> direct sql for alter partition would fail and fall back to jdo path.
