Not sure it is a smart move on Hitachi side.
I am really wondering if that is a smart move. Indeed, Pentaho might look attractive for someone who is not working with the tool on the daily basis. But once you get to know the suite a bit better, the quantity of bugs and nonexistent support from Pentaho turns one's life in daily survival. So would be interesting how HDS is planning to address that. In it's present form Pentaho is hardly a foundation to build one's business on.
