Review Comment:
No any special reason.
When working in this pr, I found there're some tests have the explain sql
logic, so I extact the logic to a explain method, and then make other tests to
call this method.

Review Comment:
Actually, I'm not sure why use reflection here.
I guess it's for compatibility for lower version hive like 1.1.0 since the
class `Registry ` is introduced in [Hive
1.2.0](https://issues.apache.org/jira/browse/HIVE-2573). Although we only
provide flink-sql-hive-connector 2.3.x and 3.1.x currenly, user may pack with
other lower version hive-exec, so I think it'll be better not to change it.
I think it's not necessary to put it in HiveShim.
