This Arithmetic Exception that you are seeing might be related to the bug
http://issues.apache.org/jira/browse/HADOOP-1122. This bug has been fixed in
release 0.13.

Thanks,
Dhruba

I've just changed dfs.replication property in the hadoop-site.xml from 1
to 2. Now I get "ArithmeticException: / by" zero when try to put
something into dfs.
 Also I want to say that both nodes are on Windows.

Subject: Why datanode does not work properly on slave?

 Hello! I'm deploying Nutch on two computers. When I run start-all.sh
script all goes good but data node on slave computer does not log
anything. All other parts of Hadoop (namenode, jobtracker, both
tasktrackers and datanode on master) log their information properly.
 Also, when I put some files from local file system into hadoop fs they
are put only into master's data folder. Slave's data folder is empty.
 At the same time when I run stop-all.sh script I get message, that
slave's datanode is being stopped. It means that it has been running
before.
 Do you know what may cause this problem?
