Hi [~stigahuang] can you please let me know what documentation you are referring here? what's the hive version you are using to  repro the test? I did try on hive-3.1 and for me its working as expected
{code:java}
// select mask('ABC-abc-0000123');

|       _c0        |
+------------------+
| XXX-xxx-nnnnnnn  |
