Hi, Given that from Node 2 you haven't said _what_ process showed that issue, whether it is the DataNode or a Client.
You probably have: 1. Not formatted your NameNode and hence the NameNode hasn't even started. Check your NN logs and re-follow the tutorial to the word, in this case. 2. A firewall. You haven't disabled, or properly configured your firewall between the nodes. Check your firewall settings in this case.
