Description

There seems to be a trivial fault in the single node cluster setup document on branch-2.
"Setup passphraseless ssh" says as follows:

      $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
      $ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
      $ export HADOOP\_PREFIX=/usr/local/hadoop

But it should be:

      $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
      $ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
      $ chmod 0700 ~/.ssh/authorized_keys
