Description

Create a HIVE view:

hive> create table bad as select 1 x, null z from dual;

Because there's no type, Hive gives it the VOID type:

hive> describe bad;
OK
x int
z void

In Spark2.0.x, the behaviour to read this view is normal:

spark-sql> describe bad;
x int NULL
z void NULL
Time taken: 4.431 seconds, Fetched 2 row(s)

But in Spark2.1.x, it failed with SparkException: Cannot recognize hive type string: void

spark-sql> describe bad;
