确认主机名是否与要求一致：

[my@Hadoop102 ~]$ hostname

Hadoop102

[my@Hadoop102 ~]$

若不一致，可进行如下操作，编辑hostname文件，输入需要的主机名称（需重启生效）：

[my@Hadoop102 ~]$ sudo vi /etc/hostname

[sudo] my 的密码：

Hadoop102

~                                                                                                                           

~                                                                                                                                                                                                                                                       

~                                                                                                                           

"/etc/hostname" 1L, 10C

编辑hosts文件（便于使用域名解析对应主机ip），如下加入Hadoop集群主机列表：

[my@Hadoop102 ~]$ sudo vi /etc/hosts

[sudo] my 的密码：

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

#Hadoop集群主机列表
