> Analogous to the Unordered case we should not have empty partition
> entries/segments in the Ordered/DefaultSorter case. This will save writing
> unnecessary data.
> Additionally, with tez_shuffle feature (TEZ-3334), in a heavily auto reduced
> job, this change would allow not fetching empty partitions and then throwing
> them away.
