URL: https://github.com/apache/shardingsphere/issues/10314


   ## Bug Report
   1.I use the master version of  shardingsphere-scaling to test database 
scaling.I have a table which has a column like this:
   `client_type` TINYINT(2) NULL DEFAULT '-1';
   
   2.when running shardingsphere-scaling transfer '-1'  value to '255' 
value.Then the sql will transfer like this：
   insert into test(id,client_type) values(1,255)......;
   
   3.I found that MySQLTinyBinlogProtocolValue.java use MySQLPacketPayload   
readInt1() to read the value，but MySQLPacketPayload use ‘readUnsignedByte()’  
to read value.
   
   4.MySQLShortBinlogProtocolValue and other may have the same problem.
