<p>Just for information purposes:</p>
<p>If you get the error "Can't connect to 127.0.0.1:50000" when adding a node to an existing cluster, you should check the SSH connection between the two nodes.</p>
<p>Try</p>
<p>#sshd -d -p 1234</p>
<p>on the node, and on the master</p>
<p># ssh -p 1234</p>
<p>and see what problems you might have building a connection.</p>
