报错原因
在浏览器中输入虚拟机主机ip：50070出现以下内容，说明是由于Hadoop进入安全模式而导致hive初始化失败。
解决方案
退出Hadoop安全模式：使用stop-dfs.sh命令关闭Hadoop服务然后用start-dfs.sh命令重启（只重启第一台机器就可以），再次在浏览器中输入虚拟机主机ip：50070进行服务验证，括号内由standby变为active即为成功。
如果重启Hadoop服务没有退出安全模式可以在hdfs-site.xml配置文件中加入以下代码退出

<name>dfs.ha.automatic-failover.enabled.ns</name>
<value>true</value>
</property>
