解决方法：
1. 检查hive server2是否启动：
netstat -anp |grep 10000
2. 检查conf/hive-site.xml 下的配置是否正确：
<configuration>
<property> <name>hive.server2.thrift.port</name>
<value>10000</value>
</property>
<property>
<name>hive.server2.thrift.bind.host</name>
<value>192.168.206.128</value>
</property>
</configuration>
