> There seems to be a trivial fault in the single node cluster setup document on branch-2.
> "Setup passphraseless ssh" says as follows:
> {code}
>       $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
>       $ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
>       $ export HADOOP\_PREFIX=/usr/local/hadoop
> {code}
> But it should be:
> {code}
>       $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
>       $ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
>       $ chmod 0700 ~/.ssh/authorized_keys
> {code}
