Working it agrees http://www.ibm.com/developerworks/ru/library/l-hadoop-1/ at first I entered into the user of hadoop by means of a command
root@one: /volumes# su hadoop
The invitation was as a result displayed
root@one: /volumes#
and to check I entered into the user of hadoop
executed the whoami
command, on what gave out me hadoop
. Then I tried to execute
root@one: /volumes# ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
therefore I received the following messages
Generating public/private dsa key pair.
open /root/.ssh/id_dsa failed: Permission denied.
Saving the key failed: /root/.ssh/id_dsa
Нow to eliminate this error?
Does that file already exist? If so, are you able to
rm
it? – chrisaycock – 2013-01-22T15:55:09.560
