> 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.
