当MYSQL具有这样的记录时，SQOOP如何决定数据拆分？

Question

select * from EMP_TEST order by EMPNO asc;
+------------+-------+----------+------+-------------+------+------+--------+
| EMPNO      | ENAME | JOB      | MGR  | HIREDATE    | SAL  | COMM | DEPTNO |
+------------+-------+----------+------+-------------+------+------+--------+
| 6765423233 | WARD  | SALESMAN | 7698 | 22-FEB-1981 | 1250 |  500 |     30 |
| 6767891234 | WARD  | SALESMAN | 7698 | 22-FEB-1981 | 1250 |  500 |     30 |
| 6767891236 | WARD  | SALESMAN | 7698 | 22-FEB-1981 | 1250 |  500 |     30 |
| 7767891234 | WARD  | SALESMAN | 7698 | 22-FEB-1981 | 1250 |  500 |     30 |
| 8767891230 | WARD  | SALESMAN | 7698 | 22-FEB-1981 | 1250 |  500 |     30 |
| 8767891233 | WARD  | SALESMAN | 7698 | 22-FEB-1981 | 1250 |  500 |     30 |
| 9765423233 | WARD  | SALESMAN | 7698 | 22-FEB-1981 | 1250 |  500 |     30 |

• 如果我参考以下示例，如何计算拆分？*

例如： 假设：最小值= 0，最大值= 400，no_of_mappers = 4 split_size =（400 – 0）/ 4 = 100

因此，拆分：[0，100），[100，200），[200，300），[300，400]
