Dear all, I am trying to set up hadoop on a 18 node cluster.
The problem is that cluster nodes do not have public IPs, such as, in order to access node1, I had first to connect to the frontal node. Let a be the ip address of my frontal node. I have configured my .ssh/config with proxycommand: # Cluster Host node*.a ProxyCommand ssh -q a /usr/bin/nc `echo %h | cut -d"." -f1` 22 # and added 3 nodes in the masters conf/slave: node001.a node002.a node003.a then I have formatted my namenode and started dfs. the issue, is that when I look for datanodes, there is only one instead of 3... the displayed datanode name changes every time that I want to display the datanodes lit. Any Idea, how to resolve this issue?? I am suspecting the framework not differentiating hosts since I used the proxycommand. Bests, Trad Mohamed Riadh, M.Sc, Ing.
