嗨，我正在使用MySQL批量加载器将数据从 Amazon 服务转储到 linux 服务器上的本地表，但是每次执行它时，它都会在 MySQL 批量加载器步骤中失败，说

 MySQL Bulk Loader - java.lang.ArrayIndexOutOfBoundsException: -1

错误日志说

ERROR 17-12 05:46:49,041 - MySQL Bulk Loader - Error in step, asking everyone to stop because of:

任何人都可以帮助为什么这个数组索引越界错误即将到来，我已经验证了前面的行，有很多行并且它们都没有空值
