   Btw, in the original JIRA comment, someone claims that Hive supports duplicate column names. I want to confirm but get:
   
   ```
   hive> create view test_view (c1, c2) as select c1, c1 from test;
   FAILED: SemanticException [Error 10036]: Duplicate column name: c1
   ```
   
   I test with Hive 2.1. Does only newer Hive support the feature?
