I never configure the ssh feature.
Not for running on a single node and not for a full size cluster.
I simply start all the required deamons (name/data/job/task) and configure = them on which ports each can be reached.

=A0Hi,

I have a dedicated= user on Linux server for hadoop. I am installing it in psedo distributed m= ode on this box. I want to test my programs on this machine. But i see that= in installation steps - they were mentioned that SSH needs to be configure= d. If it is single node, I dont require it ...right? Please advise. =

I was looking at t= his site

It menionted like = this -

Hadoop requires SSH access to manage its nodes, i.e. remote machines p= lus your local machine if you want to use Hadoop on it (which is what we wa= nt to do in this short tutorial). For our single-node setup of Hadoop, we t= herefore need to configure SSH access to localhost for the hduser user we created in the previous section.
