> ARROW-10438 made is so that a "null" in a partition column will be mapped to a special directory with hive partitioning. By default this is __HIVE_DEFAULT_PARTITION__ but it is configurable by other hive manipulation tools (e.g. spark) and so needs to be configurable in Arrow as well. The `null_fallback` option is a string that can be passed to {color:#000000}HivePartitioning::HivePartitioning and HivePartitioning::MakeFactory
> This option should be exposed in R.{color}
