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.

Sounds like your entropy pool is exhausted blocking the process. What sort
of hardware/os combo are you running this on?

I am using the cluster of the Lab of my university, so I have limited access to
its settings.
It consists of 10 nodes with Intel Xeon CPUs and GNU/Linux 2.6.38
Is there a way to solve the problem without changing the settings of the
cluster?
I am trying to use the patch that Harsh J sent me
I installed the patch:
https://issues.apache.org/jira/browse/HDFS-1835
that Harsh J told me and now everything works great!!!
I hope that this change won't create other problems.
Thanks to everyone and especially to Harsh J!!
I would never find the problem without your help!!

Hello,
I am trying to set up Hadoop HDFS in a cluster for the first time. So far I was

following:

also?
