Hi All, The Quick Start page http://hadoop.apache.org/common/docs/current/quickstart.html contains a suggestion on how to ssh to localhost w/o a passphrase
Now check that you can ssh to the localhost without a passphrase: $ ssh localhost If you cannot ssh to localhost without a passphrase, execute the following commands: $ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa $ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys I suggest adding a third command to to the snipped $ chmod 600 ~/.ssh/authorized_keys Otherwise the number of users who wants a quick start and run into an ssh issue like one described in http://www.linuxquestions.org/questions/linux-newbie-8/ssh-to-localhost-without-password-802067/ will grow on.
