Re: Problem in setting up Hadoop Multi-Node Cluster using a "ROUTER"
I'm able to make it work with a simple router without issues (Works just as well as vmnet8). Beyond Junping's point, also check that you don't have a firewall acting between your nodes.

RE: Problem in setting up Hadoop Multi-Node Cluster using a "ROUTER"
Hi Guruprasad, Do you have the valid IP<-->hostname setting in /etc/hosts so that each nodes can be accessed by hostname? I guess the configuration over public network can work may because it can get hostname resolved by DNS.

I have facing a problem on installation of hadoop multinode cluster when I connecte all the linux box througth a router. I have succeeded in installing single node cluster and multi node cluster over internet(LAN). I want to test the multi node cluster by establishing private network between all the nodes through a router which assigns private IP address. I am keeping the same configuration which i used to test multi node cluster over internet(LAN). Error: With the router setup wen i run word count example, the program gets hanged in the middle. it will complete map 100% and will get stop when reduce reaches around 20%. I gave namenode format many times and tried to run the program but still no luck :(. one unlucky thing is there is no error in log files of both master and slave machine. Please let me know what could be the problem. Quick response is very much appreciated. Thanks & Regards, Guruprasad
Problem in setting up Hadoop Multi-Node Cluster using a "ROUTER"
Hello everyone. I have facing a problem on installation of hadoop multinode cluster when I connecte all the linux box througth a router. I have succeeded in installing single node cluster and multi node cluster over internet(LAN). I want to test the multi node cluster by establishing private network between all the nodes through a router which assigns private IP address. I am keeping the same configuration which i used to test multi node cluster over internet(LAN). Error: With the router setup wen i run word count example, the program gets hanged in the middle. it will complete map 100% and will get stop when reduce reaches around 20%. I gave namenode format many times and tried to run the program but still no luck :(. one unlucky thing is there is no error in log files of both master and slave machine. Please let me know what could be the problem. Quick response is very much appreciated. Thanks & Regards, Guruprasad
