> I have the following json file
> bug.json
> {"col" : {"name" : "foo", "id": 1}, "col1": 1}
> {"col" : {"name" : "bar", "id": 2}, "col1": 2}
> Have the same data in another file bug1.json.
> The following query succeeds and returns the right result.
> select b.col from dfs.`bug.json` b, dfs.`bug1.json` b1 where b.col1 = b1.col1;
> However selecting an individual field from the 'col' map fails.
> select b.col.name from dfs.`bug.json` b, dfs.`bug1.json` b1 where b.col1 = b1.col1;
> Below is the stack trace
> java.lang.IllegalStateException
> Incoming batch has an empty schema. This is not allowed.
