hostname 问题 不知道如何处理了

[root@chen hbase-0.94.0]# bin/start-hbase.sh
master: starting zookeeper, logging to /usr/local/hbase-0.94.0/bin/../logs/hbase-root-zookeeper-chen.ranm.out
starting master, logging to /usr/local/hbase-0.94.0/logs/hbase-root-master-chen.ranm.out
slave2: starting regionserver, logging to /usr/local/hbase-0.94.0/bin/../logs/hbase-root-regionserver-Slave.Hadoop.out
#localhost: ssh: #localhost: Temporary failure in name resolution
              
               
               

            
[Hadoop@chen hbase-0.94.0]$ ssh hostname
ssh: hostname: Temporary failure in name resolution
        

            有人知道怎么弄吗
        

            你可以直接ssh ip试试。如果ip可以，那就是没有配置ip和name的对应关系，到/etc/hosts配置
