Я пытаюсь настроить Версия Hadoop 0.20.203.0 в псевдораспределенной конфигурации с использованием следующего руководства:

http://www.javacodegeeks.com/2012/01/hadoop-modes-explained-standalone.html

После запуска сценария start-all.shя запускаю "jps".

Я получаю этот вывод:

4825 NameNode
5391 TaskTracker
5242 JobTracker
5477 Jps
5140 SecondaryNameNode

Когда я пытаюсь добавить информацию в hdfs с помощью:

bin/hadoop fs -put conf input

Я получаю сообщение об ошибке:

Я не совсем уверен, но я полагаю, что это может быть связано с тем фактом, что узел данных не работает.

Кто-нибудь знает, что я сделал не так или как решить эту проблему?
