ERROR---mariadb主从复制ERROR: No query specified

mariadb主从复制同步时出现以下错误：

        ERROR:No query specified

MariaDB [(none)]> show slave status\G;
*************************** 1. row ***************************
               Slave_IO_State: Connecting to master

ERROR: No query specified

出现这个问题是因为在执行命令：show slave status\G；时多加了一个（;）分号导致的，去掉分号错误就没有了！！！
