> I ran into this while testing some hive features.
> Whether we use hiveinputformat or combinehiveinputformat, a split cannot be less than a dfs block size.
> This is a problem if we want to increase the block size for older data to reduce memory consumption for the
> name node.
> It would be useful if the input split was independent of the dfs block size.
