   ### Version
   
   1.2.4.1
   
   ### What's Wrong?
   
   When querying an external table of hive, if hive uses the apache tez engine 
and the union syntax, the data path of the hive partition table is similar to: 
"hdfs://testcluster/warehouse/edw/dwd/dwd__data__instance_mapping__nd/dt=1900 
-01-01/HIVE_ UNION_ SUBDIR_ 1/000000_0"
   execute query sql:SELECT * FROM 
hive_catalog.edw.dwd__data__instance_mapping__nd;
   error info:errCode = 2, detailMessage = Fail to parse columnsFromPath, 
expected: [dt], filePath: 
hdfs://testcluster/warehouse/edw/dwd/dwd__data__instance_mapping__nd/dt=1900-01-01/HIVE_UNION_SUBDIR_1/000000_0
   
   ### What You Expected?
   
   Previously, there was support for HIVE external tables. I hope HIVE_ Catalog 
can also support the same
