There is no other information in the log (although when I run it on my pc and
it works, there is more information in the log) and also the web page of the
namenode doesn't contain any live datanodes as it should.
That's why I said it freezes... I have no idea what is going on...
Please if anyone can help because it is really important to make it work as
soon as possible (for my diploma thesis) and I really have no idea what might
go wrong.
