Subject Switch and configure single node and cluster XML configuration
Date Fri, 10 Jan 2014 13:36:19 GMT

I have a workstation and a laptop. I have installed 2.1.1 release on 
both computers. Now I want to test single node and cluster setup. I am

Workstation connected to router via ethernet.
Laptop connected to router via wireless.

LAN broadcast ip :
Workstation will act as the master in cluster setup with ip:
Laptop ip:
Operating systems : Ubuntu 13.04 distribution of Linux operating system.

successfully working) Namenode failed to start on the workstation.

node on the laptop with IP address instead of 
hence failed to connect to port 22. ( using instead of

Am I configuring the hdfs-site.xml correct ?
