## Bug Report
**For English only**, other languages will not accept.
Before report a bug, make sure you have:
- Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues).
- Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview).
Please pay attention on issues you submitted, because we maybe need more details.
If no response anymore and we cannot reproduce it on current information, we will **close it**.
Please answer these questions before submitting your issue. Thanks!
### Which version of ShardingSphere did you use?
master
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
<img width="1387" alt="image" src="https://user-images.githubusercontent.com/86462784/177316136-75127397-7fd7-4818-a493-a78eeb704cdb.png">
### Actual behavior
<img width="1227" alt="image" src="https://user-images.githubusercontent.com/86462784/177316107-88f3bf61-b711-46b8-ac23-fae53148f70d.png">
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
1. buidl MySQL MGR
2. BUild Proxy cluster
3. start scaling job
4. shutdown slave node of MGR
5. shutdown master node of MGR
