Subject RE: Datanode doesn't start but there is no exception in the log
Date Fri, 13 May 2011 08:28:02 GMT

There is no shutdown message until I shutdown the DataNode.

I used hostname of the machine that will run the DataNode and I now used the IP but there
is no difference.
Again the DataNode seems to freeze and the output at the log is the one I mentioned before.
