Review Comment:
I meet this exception when I insert rows into olap table if the tablet not
exist in backend of the instance:
```sql
CREATE TABLE `a4` (
`date_time` date NULL
) ENGINE=OLAP
DUPLICATE KEY(`date_time`)
PARTITION BY RANGE(`date_time`)
(PARTITION p1 VALUES [('0000-01-01'), ('2020-01-02')),
PARTITION p2 VALUES [('2020-01-02'), ('2020-01-03')),
PARTITION p3 VALUES [('2020-01-03'), ('2020-01-04')))

```
for the above sql, I have 2 backends in doris(192.168.126.2 and
192.168.126.3), and create `a4` with one tablet(exists in 192.168.126.2), the
insert statement will select a random backend to execute. when the backend of
the instance not contains the tablets of `a4`, you will meet the exception
