Установил Hadoop на Windows (http://javacore.ru/topic/117-hadoop.htm). namenode и cluster запускается нормально.
А где команды вводить (например, загрузить файл в HDFS)? Где расположена консоль?

Answer 2

Use start-dfs.sh on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file. Use start-mapred.
