我无法运行start-dfs.sh

ubuntu@UBUNTU:~$ start-dfs.sh
14/10/19 19:26:50 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

我在安装hadoop时做了以下事情：

ssh-keygen -t rsa -P ''
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

ssh localhost是否有效？我猜不会。你必须先做好这项工作。您必须具有公钥/私钥集的工作组合。有关详情，请访问Google passwordless SSH login或在此处查看示例：http://rcsg-gsir.imsb-dsgi.nrc-cnrc.gc.ca/documents/internet/node31.html
