   BE can't be grayscale upgraded even if I using the latest code.
   
   I upgraded one BE from 0.8.2.1 to latest version.
   
   When I query,  mysql client error is following;
   
   ```
   ERROR 1064 (HY000): Ocurrs time out with specfied time xxx MILLISECONDS
   or
   ERROR 1064 (HY000): failed to send batch
   ```
   The latest BE warning logs:
   ```
   W1109 14:43:35.397363 28981 data_stream_sender.cpp:125] failed to send brpc batch, error=No such method, error_text=[E1002][10.24.
   104.124:8060][E1002]Fail to find method=doris.PInternalService/transmit_data
   ```
   The 0.8.2.1 BE warning logs
   ```
   W1109 14:43:37.406872 10384 data_stream_sender.cpp:149] failed to send brpc batch, error=No such method, error_text=[E1002][10.20.93.37:8060][E1002]Fail to find method=palo.PInternalService/transmit_data
   ```
   
   The cause for this error is obvious， So I think this issue have not  been fixed completely.
