Brent,

that would be to use the HBase experimental triple store, but has nothing
to do with HDFS.

In the Marmotta LDP implementation you can use any of the available triple
stores for storing LDP-RSs, but that's not necessarily bound to the
implementation used for storing LDP-NRs. In that schema, by default
Marmotta uses H2/Postgres and local file system respectively.

Hope this helps to understand the difference.

Cheers,
