> Consider the following json file:
> {"rownum":1, "arrayval": [ {"val1":"a1"}, {"val1":"a2"} ]}
> {"rownum":2, "arrayval": [ {"val1":"b1"}, {"val1": "b2"} ]}
> If we have the following query, we will fail with a class cast exception.
> select rownum, table.arrayval.val1 from dfs.`input.json` as table;
> We should return an array of type 'val1' like the following
> [a1, a2]
> [b1, b2]
