    Assignee: Marcelo Vanzin

> Spark-sql do not support for void column datatype of view
> ---------------------------------------------------------

>                 Key: SPARK-20680
>                 URL: https://issues.apache.org/jira/browse/SPARK-20680
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 2.1.0, 2.1.1
>            Reporter: Lantao Jin
>            Assignee: Marcelo Vanzin
>            Priority: Major
>
> Create a HIVE view:
> {quote}
> hive> create table bad as select 1 x, null z from dual;
> {quote}
> Because there's no type, Hive gives it the VOID type:
> {quote}
> hive> describe bad;
> OK
> x     int     
> z     void
> {quote}
> In Spark2.0.x, the behaviour to read this view is normal:
> {quote}
> spark-sql> describe bad;
> x       int     NULL
> z       void    NULL
> Time taken: 4.431 seconds, Fetched 2 row(s)
> {quote}
> But in Spark2.1.x, it failed with SparkException: Cannot recognize hive type 
> string: void
> {quote}
> spark-sql> describe bad;
