本文讲述了Hive启动时遇到的连接错误，原因是未先启动Hadoop Namenode。解决方法是启动Hadoop集群。核心在于理解Hive依赖关系及集群启动顺序。

hive启动报出Exception in thread "main" java.lang.RuntimeException: java.net.ConnectExcepti on: Call From hadoop101/192.168.128.100 to hadoop101:9820 failed on connection exception: java.net.ConnectException: 拒绝连接;

原因分析：因为在启动hive之前没有先启动namenode，因为hive的运行是基于Hadoop集群

解决方案：启动hadoop即可。

解决：关闭Hadoop安全模式，虽然我的默认关闭，但我还是重新运行下面的代码，可以进入hive，但是还是有错误，太难了明天再弄。解决：Hadoop没有启动启动之后就可以了，但我又出现了另一种错误，哭死。网上说是hadoop和hive的guava.jar版本不一致。
