Sandy, I have no idea about your issue :(
Zander,
Your problem is probably about this JIRA issue:
http://issues.apache.org/jira/browse/HADOOP-1212
Here is 2 workarounds explained:

As far as I know, datanodes just know the block ID, and the namenode knows
which file this belongs to.

Where are your namenode and datanode storing the data? By default, it goes
into the /tmp directory. You might want to move that out of there.

Hi all,
I consistently have this problem that I can run HDFS and restart it after

Is that normal? Maybe this is treated as temporary data, and the results

Another question now. Do the datanodes have any way of linking a particular

Matei is referring to fact that a malicious peace of code can bypass the
Name Node and connect to any data node directly, or probe all data nodes for
that matter. There i
i resolved this issue by appending .local to the target hostname when i ssh.
for example my nodes are node0 and node1 thus i am successful when i ssh
node0.local and node1.local. outupt is as given in tutorial.

Hi Rasit,
Thanks for your response!
I saw the previous threads by Jerro and Mithila, but I think my problem is
slightly different. My datanodes are not being started, period. From a
previous thread:
"The common reasons for this case are configuration errors, installation
errors, or network conne

Yes, I've tried the long solution;
when I execute ./hadoop dfs -put ... from a datanode,
in any case 1 copy gets written to that datanode.
But I think I should use SSH for this,
Anybody knows a better way?
Thanks,

If you can't ssh directly to node1's IP address, then it seems you have a
basic network configuration issue which is really outside the scope of
Hadoop setup. In general, you should make sure that:
0) nodes are physically connected (use crossover cable if necessary)
1) your nodes are configured f
That's awkward , the site went down!
and ok, I note these points ,for future.

Hi All
I'm trying to create a tiny 2-node cluster (both on linux FC7) with Hadoop
0.19.0 - previously, I was able to install and run hadoop on a single node.
Now I'm trying it on 2 nodes - my idea was to put the name node and the job
tracker on separate nodes, and initially use these two as the da
Sandy, as far as I remember, there were some threads about the same
problem (I don't know if it's solved). Searching the mailing list for
this error: "could only be replicated to 0 nodes, instead of 1" may
help.

Thanks, Jeff.
After considering JIRA link you've given and making some investigation:
It seems that this JIRA ticket didn't draw much attention, so will
take much time to be considered.
After some more investigation I found out that when I copy the file to
HDFS from a specific DataNode, first copy
