hey hadoop users i need some help for running multi node hadoop
I'm following

http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-
multi-node-cluster/

I have a hadoop cluster(2 nodes) but I ran jps on the master node and slave
node but not all process are started

master:
22160 NameNode
22716 Jps
22458 JobTracker

slave:
32195 Jps

the slave node is not detecting datanode? can anyone help?

Hello Kshitij,

  What exactly is the error. It's quite difficult to say anything without
having any idea about the actual error. There could be n reasons for that.

Regards,

Look at your TaskTracker and DataNode logs. Going by the instructions on the page you linked, they should be in /usr/local/hadoop/logs.
