------------------------------------------------------------------

It's suspicious that it would work with auto-create but not with a script, which has nothing to do with DN as such.
I wonder if the syntax in the script (""COLUMN_TYPE" character varying(128) DEFAULT NULL::character varying) has anything to do with it? Should we change these to NULL and would it help?

Can you reference a DN bug if you file one?

> With the upgrade to  datanucleus 4.x versions in HIVE-6113, hive does not work properly with postgres.
> The nullable fields in the database have string "NULL::character varying" instead of real NULL values. This causes various issues.
> One example is -
> {code}
> hive> create table t(i int);
> OK
> Time taken: 1.9 seconds
> hive> create view v as select * from t;
> OK
> Time taken: 0.542 seconds
> hive> select * from v;
> FAILED: SemanticException Unable to fetch table v. java.net.URISyntaxException: Relative path in absolute URI: NULL::character%20varying
> {code}
