Hadoop 配置完成后，出现slave无法建立的问题。

[root@namenode1 bin]# ./start-all.sh
starting namenode, logging to /usr/program/hadoop1/libexec/../logs/hadoop-root-namenode-namenode1.out
(10.102.10.35)' can't be established.
RSA key fingerprint is a5:09:19:d2:ed:d4:54:b1:f7:8c:c6:2e:9e:6d:66:a5.
: starting datanode, logging to /usr/program/hadoop1/libexec/../logs/hadoop-root-datanode-localhost.out

说明：本地机器1台，配置为master，ip地址10.102.10.34，本地机器虚拟1个slave，ip地址10.102.10.35，然后远程端机器1台slave，ip地址10.211.40.6。参照一些配置顺序的教程后，出现上述问题。因为是新手，想请教下问题在哪，或者能否有成功的朋友，给个可以实现的教程，我学习下，谢谢各位。

相互之间登录是可以的，但是只要 start-all.sh 就出现上述错误。

我按照这个完成以后，出现JAVA_HOMe 没有被设置和找到的错误，请问下，你知道这是什么原因么？

这个最后出现JAVA_HOME 没有设置和找到，但是我检查了，这个应该是配置好了的。请问是怎么回事呢？

[root@master sbin]# ./start-dfs.sh

检查Java是否存在多个版本

谢谢，已经按照这个提示，自行解决了，配置成功。
