Weston Pace closed ARROW-13771.
-------------------------------
Resolution: Invalid
I was turned around. The directory partitioning factory needs names because
they cannot be inferred from the filenames. The fact that the hive
partitioning doesn't need names is a good thing and not something we want to
undo.
> [C++] Allow HivePartitioningFactory to be created from a vector of names

> The DirectoryPartitioningFactory already supports this (types are inferred at
> runtime). Both factories simply extend KeyValuePartitioningFactory which is
> doing all the heavy lifting. This should be pretty straightforward.
