   Ah yes, there are all kinds of inconsistencies in the PySpark Row class.  I think this is a duplicate of SPARK-22232 and we discussed in the PR here https://github.com/apache/spark/pull/20280. The fix there was to also pickle the `__from_dict__` flag, but the problem becomes that the input schema in `createDataFrame` must match field names and no longer goes off of position.  At the time, I thought this was the most consistent fix, but I'll have to look at it again.
