Question

hadoop start-all.sh 现这个错误 ssh 免密码登入已经做好了 请各位大神帮帮忙啊 谢谢啦

执行 start-all.sh 就出现下面的错误
starting namenode, logging to /home/Hadoop/hadoop-1.2.1/libexec/../logs/hadoop-hadoop-namenode-master.out
The authenticity of host 'slave2 (192.168.1.12)' can't be established.
RSA key fingerprint is e4:61:02:27:09:08:a6:20:9b:71:e5:1f:bd:5a:1d:91.
Are you sure you want to continue connecting (yes/no)? slave1: starting datanode, logging to /home/Hadoop/hadoop-1.2.1/libexec/../logs/hadoop-hadoop-datanode-slave1.out

下面这是日志文件显示：

Answer 1

应该是ssh免密码登陆没做好吧，或者是没有权限访问文件什么的，确定都是用同一个用户创建的Hadoop文件。还有，这事儿表问度娘

追问

问题解决了 虽然不是你说的解决方案
但还是谢谢了
