Thank you for posting those , you da true MVP ! <| sep |> I think the biggest reason is crossplatform . Hadoop is geared to be a heterogeneous cluster of machines . With Java I can guarantee that every machine is running the same code , which solves quite a few portability headaches . <| sep |> Yeah he only had the intent of making a few tracks like dog blood , I don ' t think he ever wanted to make an act out it <| sep |> It ' s true that their corporate taxes are below 22 %, but they have more than one tax and they are accumulative . Assume you ' ve earned 1 million , after the corporate tax you will have 780000 left . If you grab it , you are encumbered with 30 % profit tax . And now you ' re down to 546000 . And then a general payroll tax of 31 . 2 % because you ' re treated as if you were your own employee . That leaves you with 375648 out of 1 million . So you have now payed over 60 % of the initial sum in tax .
