Description
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.
