Yes, that's exactly what I described
https://github.com/apache/spark/pull/4892/files#diff-27c76f96a7b2733ecfd6f46a1716e153R201
But the bug you raised in #4892 is quite interesting
```scala
sqlContext.jsonRDD(sc.parallelize("""{"a": {"a": {"a": 1}}, "c": 1}""" ::
Nil)).registerTempTable("nestedOrder")
sqlContext.sql("SELECT a.a.a FROM nestedOrder ORDER BY a.a.a")
```
Anyway, I will do some investigation on some other database systems other
than Hive.
