passphraseless ssh
I tried the following:
*
hadoop-1.1.1/docs/single_node_setup.html
in order for passphraseless ssh to work, the below is not sufficient:
Setup passphraseless ssh
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 recommend you add the following sentence:
remove write permissions from group and other to your home directory and
.ssh directory.*

Since $HOME/.ssh should never be accessible for anyone but the owner,
nothing has to be remover. In case you've changed permissions for
whatever reason, you have to revert these changes, but this is generally
true for all SSH application.
