Subject Documentation suggestion: Quick start
Date Wed, 25 Aug 2010 07:16:21 GMT
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.  WBR Oleg V. Zhylin   ovz@yahoo.com
