On the machine ( named Monkey) when I am starting the NodeManager I am getting the following error - org.apache.hadoop.yarn.exceptions.YarnRuntimeException: java.net.NoRouteToHostException: No Route to Host from monkey/192.168.56.154 to horse:8700 failed on socket timeout exception: java.net.NoRouteToHostException: No route to host; For more details see: http://wiki.apache.org/hadoop/NoRouteToHost I verified the config files and also the communication between the four nodes. Which configuration file this error would be thrown ? Please advise. Regards,Raj
