Work Description: kasakrisz commented on pull request #1446:
URL: https://github.com/apache/hive/pull/1446#issuecomment-684505690
Adding a test case for various underlying formats doesn't make sense this
case because the duplicate check is performed in the semantical analysis phase
of the `create table` statement and the error message would be the same. So if
a duplicate found the code flow doesn't reach the point where the table is
actually created.
Added a test case for nested struct.

> When you create at table with a struct with twice the same attribute name,
> hive allow you to create it.
> create table test_struct( duplicateColumn struct<id:int, id:int>);
> You can insert data into it :
> insert into test_struct select named_struct("id",1,"id",1);
> But you can not read it :
> select * from test_struct;
> Return : java.io.IOException: java.io.IOException: Error reading file:
> hdfs://.../test_struct/delta_0000001_0000001_0000/bucket_00000 ,
> We can create and insert. but fail on read the Struct part of the tables. We
> can still read all other columns (if we have more than one) but not the
> struct anymore.
