部署amoeba过程中若出现错误：
ERROR 1044 (42000): Could not create a validated object, cause: ValidateObject failed
或
ERROR 1044 (42000): poolName=multiPool, no valid pools
解决办法：
dbServers.xml中的用户，需要在主从机上分配权限。
mysql>GRANT ALL PRIVILEGES ON *.* TO ‘user‘@‘%‘ IDENTIFIED BY ‘password‘ WITH GRANT OPTION;
amoeba ERROR 1044 (42000): Could not create a validated object, cause: ValidateObject failed
