启动hadoop遇到的问题

启动：

cd /usr/lib/hadoop/hadoop-1.0.3
bin/start-all.sh

命令在普通模式下运行是这样的

wang@ubuntu:~$ cd /usr/lib/hadoop/hadoop-1.0.3

wang@ubuntu:/usr/lib/hadoop/hadoop-1.0.3$ bin/start-all.sh

starting namenode, logging to /usr/lib/hadoop/hadoop-1.0.3/libexec/../logs/hadoop-wang-namenode-ubuntu.out

wang@ubuntu:/usr/lib/hadoop/hadoop-1.0.3$ jps
4819 Jps

肯定不对了就这一个

在su root 模式下运行是
root@ubuntu:/usr/lib/hadoop/hadoop-1.0.3# bin/start-all.sh
starting namenode, logging to /usr/lib/hadoop/hadoop-1.0.3/libexec/../logs/hadoop-root-namenode-ubuntu.out
root@localhost's password:

额要密码，我不知道怎么办了，因为初学，还是为别人弄的，我自己也有许多论文要看没时间研究，所以希望大神给点提示看看怎么弄。
总之先谢了

建议安装hadoop2,参考这个文档

要密码输入密码即可
不要随便切换用户，否则会遇到权限问题。

参考这个文档

但是默认设置的是不需要密码的就是那个localhos，
开启ssh的时候设置的，我见别人都是用root方式运行的bin/start-all.sh
请问用该用哪种方式啊，
是直接bin/start-all.sh
还是 sudo bin/start-all.sh
还是su root 后bin/start-all.sh
