报错如下：

WARN jdbc.HiveConnection: Failed to connect to slave3:10000
Could not open connection to the HS2 server. Please check the server URI and if the URI is correct, then ask the administrator to check the server status.
Error: Could not open client transport with JDBC Uri: jdbc:hive2://slave3:10000: java.net.ConnectException: 拒绝连接 (Connection refused) (state=08S01,code=0)

原因是因为hive服务没有启动

执行命令：hive --service hiveserver2 &

客户端连接成功
