Hadoop 2.6.0-运行启动脚本时询问用户密码? [英] Hadoop 2.6.0 - Asking password for the user while running the start up script?

问题描述

我已经在ubuntu linux上以伪分布式模式安装了hadoop 2.6.0.除了这个问题，一切都很好.当我运行start-dfs.sh脚本启动守护程序时，它要求输入Linux用户密码.不知道为什么吗?它要求每个守护程序(名称节点，数据节点和秒名称节点)输入密码.您能帮忙解决这个问题吗?

I've installed hadoop 2.6.0 in ubuntu linux on a pseudo distributed mode. Everything is fine except this issue. When I run the start-dfs.sh script to start daemons it's asking for the linux user password. Not sure why? It's asking for the password for every daemon (namenode, datanode & sec namenode). Could you please help to address this issue?

huser@ubuntu:~/hadoop$ sbin/start-dfs.sh
Starting namenodes on [localhost]
huser@localhost's password:

谢谢.

推荐答案

如果未为huser @ localhost设置passwordless ssh，则会发生这种情况. getenfor

This happens if you did not setup passwordless ssh for huser@localhost. getenfor

如果您设置了passwordless ssh，请确保使用$sestatus命令禁用了selinux.

If you did setup passwordless ssh make sure selinux is disabled by using $sestatus command.

注意:您应该以sudo用户身份运行sestatus.

Note: You should run sestatus as a sudo user.
