解决办法

1. 进入到hive中conf目录下, vim hive-site.xml

<!--hive server2的超时时间，默认是5000-->
<property>
  <name>hive.server2.long.polling.timeout</name>
  <value>5000</value>
  <!--尤其注意时间是5000，原配置文件中会多个L，需要去掉-->
</property>
<!-- hive server2的使用端口，默认就是10000-->
<property>
  <name>hive.server2.thrift.port</name>
  <value>10000</value>
</property>

<!-- hive server2绑定的主机名-->
<property>
  <name>hive.server2.thrift.bind.host</name>
  <value>hadoop21</value>
</property>
