   ## Bug Report
   
   **For English only**, other languages will not accept.
   
   Before report a bug, make sure you have:

   - 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 **more than 7 days** 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?
   5.0.0-RC1
   
   ### Which project did you use? Sharding-JDBC or Sharding-Proxy?
   Sharding-Proxy
   
   ### Expected behavior
   Use master-slave rule, execute SQL `select * from t_order` return correct result.
   
   ### Actual behavior
   Can't return result and birst burst warnings.
   ```
   mysql> use master_slave_db;
   Database changed
   mysql> select * from t_order_0;
   Query OK, 0 rows affected, 25971 warnings (3 min 40.86 sec)
   ```
   
   ### Reason analyze (If you can)
   The first packet Sharding-Proxy returned is an EOF packet, that means column definition packets lost. 
   Debug in the codes, I found queryHeader size is 0. queryHeader  is obtained from meta data, master-slave mode doesn't read the meta data.
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   Config a master-rule and execute the SQL like `select * from`.
   
   ### Example codes for reproduce this issue (such as a github link).

   I guess this is a design rather than a bug...  @terrymanu
