  1. 启动hiveserver2:
    cd $HIVE_HOME bin/hiveserver2(默认是10000端口)
    sudo netstat -anp|grep 10000
  2. pyhs2连接hive，报错如下：
    raise Pyhs2Exception(res.status.errorCode, res.status.errorMessage) Pyhs2Exception: “Error while compiling statement: FAILED: SemanticException Unable to fetch table tbl_card_log. javax.jdo.JDODataStoreException: The last packet successfully received from the server was 2,450,497 milliseconds ago. The last packet sent successfully to the server was 2,450,497 milliseconds ago. is longer than the server configured value of ‘wait_timeout’. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property ‘autoReconnect=true’ to avoid this problem
    增加hiveserver2的客户端超时时间，修改hive-site.xml
    <name>hive.server.read.socket.timeout</name><value>3600s</value>
    <name>hive.server2.async.exec.shutdown.timeout</name><value>3600s</value>
    另外，设置pyhs2.connect的timeout参数
