Yup, for some reason the DN's not picking up any space stats on your platform.

Could you give me the local command outputs of the following from both
your Solaris and Linux systems?

$ df -k /opt/hadoop-install/hadoop-0.20.2/hadoop-data
$ du -sk /opt/hadoop-install/hadoop-0.20.2/hadoop-data

FWIW, the code am reading says that the DU and DF util classes have
only been tested on Cygwin, Linux and FreeBSD. I think Solaris may
need a bit of tweaking, but am not aware of a resource for this off
the top of my head.
