Если можно войти в систему с

ssh username@hostname #or 
ssh username@ip_address

, но не

ssh ipaddress

Тогда имя пользователя не является тем же как целевым пользователем на хосте, с которым Вы пытаетесь соединиться. Я вижу от Вашего вывода от ssh, что Ваш локальный пользователь hardoop, и удаленный пользователь hadoop1. Если они не то же имя, Вы должны иметь user@remote

ответ @Shutupsqaure корректен; но если Вы хотите поддержать различные имена пользователей на удаленном компьютере, можно просто редактировать/создавать $HOME/.ssh/config файл и вставить его:

Host nickname
    HostName hadoopslave 
    User hadoop1

(редактируют для Вашей ситуации, ясно).

Теперь ssh nickname совпадает с ssh hadoop1@hadoopslave.

$HOME/.ssh должен быть режим 0700---, которым это должно быть в корневом каталоге пользователя, который выходит эти ssh команда. Никакая потребность вообще для перезапуска сервиса (не смущают ssh клиент и сервер!)

Другое очень полезное ключевое слово IdentityFile---, но можно поместить более или менее каждое возможное ssh опция в том файле; Вы видите детали в man ssh.
