> CombineHiveInputFormat should combine all files inside one partition to form
> a split but should not takes files cross partition boundary. This works for
> regular table and partitions since all input paths are directory. However
> this breaks when the input is files (in which case tablesample could be the
> use case). CombineHiveInputFormat should adjust to the case when input could
> also be non-directories.
