Description
1- create and populate a hive table . I did this in a hive cli session .[ not that this matters ]
create table atable (col1 int) ;
insert into atable values (10 ) , (100) ;
2. create a view from the table.
[These actions were performed from a spark shell ]
spark.sql("create view default.aview (int1 , int2 ) as select col1 , col1 from atable ")
java.lang.AssertionError: assertion failed: The view output (col1,col1) contains duplicate column name.
