My table in hive metastore (hive_metastore.dd_omp.versioncompatibility) is an EXTERNAL TABLE. I don't understand why I can select and create table in Unity Catolog without setting hive version to 1.2.1.

I have two issues:

1) When I don't set hive version in advanced option of cluster then I got the ERROR:

"Parquet does not support timestamp. See HIVE-6384"

2) I found the solution of above issue - I need to set hive version to at least 1.2.1 in advanced option of cluster. When I did it, I got the error, which I describe in my first post.
