Yea, actually I wouldn't at least backport this to branch-2.3 since the
release is very close. Looks a bug to me as well.
One nitpicking is the case with RDD operation:
```python
>>> from pyspark.sql import Row
>>> row_class = Row("c1", "c2")
>>> row = row_class(1, 2, 3)
>>> spark.sparkContext.parallelize([row]).map(lambda r: r.c1).collect()
[1]
```
This is really unlikely and I even wonder if it makes any sense, but still
there might be a case although the creation of the namedtuple like row itself
should be disallowed, as fixed here.
Can we just simply take this out from branch-2.3?
