Установка не удалась. Не удалось получить пульс от агента

Я получил эту ошибку

Ошибка установки. Не удалось получить пульс от агента.

когда я устанавливал cloudera на одиночном node. Это то, что находится в моем файле /etc/hosts:

127.0.0.1   localhost
192.168.2.131   ubuntu

Это то, что находится в моем файле /etc/hostname:

ubuntu

И это ошибка в файле /var/log/cloudera-scm-agent:
