Table 'test._test_new' doesn't exist when add trigger (use pt-osc)

DELIMITER $$
USE `test`$$
DROP PROCEDURE IF EXISTS `kz_test`$$
CREATE PROCEDURE `kz_test`()
BEGIN
DECLARE i INT DEFAULT 1;
DECLARE a INT DEFAULT 1;
WHILE i < 1000001 DO

WHILE a < 20001 DO
SELECT CONCAT('ccccc ', i,a);
INSERT INTO test.test VALUES(CONCAT(i,a),1);
SET a = a + 1;
END WHILE;
SELECT CONCAT('aaaaa', i);
COMMIT;
SELECT CONCAT('bbbbb', i);
SET a = 1;
SET i = i + 10000;
END WHILE;
END$$
DELIMITER ;

use test;
create table test(key1 int not null, key2 int not null)engine=innodb;

first connect1:
call kz_test();

then connect 2:
use test;
create table _test_new(key1 int not null, key2 int not null)engine=innodb;
CREATE TRIGGER `pt_osc_test_test_del` AFTER DELETE ON `test`.`test` FOR EACH ROW DELETE IGNORE FROM `test`.`_test_new` WHERE `test`.`_test_new`.`key1` <=> OLD.`key1`;
CREATE TRIGGER `pt_osc_test_test_ins` AFTER INSERT ON `test`.`test` FOR EACH ROW REPLACE INTO `test`.`_test_new` (`key1`, `key2`) VALUES (NEW.`key1`, NEW.`key2`);
DROP TRIGGER IF EXISTS `test`.`pt_osc_test_test_del`;
DROP TRIGGER IF EXISTS `test`.`pt_osc_test_test_ins`;
drop table _test_new;

then conenct 1 will error ,msg : Table 'test._test_new' doesn't exist.
