mycat后台一直不停打印WARN日志（一小时几百兆），内容如下： 2019-11-29 11:06:58.622 WARN [$_NIOREACTOR-5-RW] (io.mycat.server.ServerConnection.routeEndExecuteSQL(ServerConnection.java:307)) - ServerConnection [id=11, schema=ins0, host=10.11.17.222, user=root,txIsolation=3, autocommit=true, schema=ins0, executeSql=SELECT TABLE_SCHEMA, TABLE_NAME, TABLE_TYPE FROM information_schema.TABLES WHERE TABLE_SCHEMA = 'ins0' ORDER BY TABLE_SCHEMA, TABLE_TYPE]SELECT TABLE_SCHEMA, TABLE_NAME, TABLE_TYPE FROM information_schema.TABLES WHERE TABLE_SCHEMA = 'ins0' ORDER BY TABLE_SCHEMA, TABLE_TYPE err:java.sql.SQLNonTransientException: can't find table define in schema TABLES schema:ins0

客户端登录mycat后，没有发现information_schema这个schema，请问这个是怎么生成的？

发现用Navicat客户端连接mycat时就会一直提示上面描述问题，换成SQLyog客户端就没报错了。
