Re: Getting Error in Secondary Data node
Harsh J 2012-07-16, 09:18
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.
