hadoop大佬进来看看。。。。。。。求助解答！

[root@hadoop1 sbin]# start-dfs.sh
17/12/01 22:08:31 WARN hdfs.DFSUtil: Namenode for null remains unresolved for ID null. Check your hdfs-site.xml file to ensure namenodes are configured properly.
Starting namenodes on [hadoop01]
hadoop01: ssh: Could not resolve hostname hadoop01: Temporary failure in name resolution
hadoop启动老是报这个，不知道为啥？求解？

在虚拟机里可以，而用shh老是出现报上面的错

你去/etc/hosts加下hadoop01的别名

[root@hadoop1 etc]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.74.132 hadoop1
127.0.0.1 hadoop1
[root@hadoop1 etc]# cd /etc/sysconfig/network
-bash: cd: /etc/sysconfig/network: 不是目录
[root@hadoop1 etc]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=hadoop1
[root@hadoop1 etc]#
这个嘛！加了的

话说你的etc/hosts里的HOSTNAME=hadoop1，是不写错了啊，应该是hadoop01，和core-site.xml文件中fs.default.name中主机名是一样的才行，还有要配置免密码登录

应该是hdfs-site.xml配置不对
