Open Source Hadoop Project for both HDF4 and HDF5?

I'm wondering if there has been any open source software project for
Hadoop that can work with *both* HDF4 and HDF5 directly as described
in SciMATE[1] (i.e., HDF5 Adapter in Figure 2 from the paper) I think
[2] is close but it seems to be only for NetCDF.

  p.s. I'm not looking for a solution that involves exporting data
into XML from HDF.
