Hi [~waittting], you should post this kind of question in the [user mailing 
list|https://flink.apache.org/gettinghelp.html#user-mailing-list] instead of 
JIRA. Besides, I suggest you post more information about the question to help 
others identify the problem, e.g. the exception stack, the sample code, etc.

> When I used 'flink run --python' to test my connector, I got an error '{*}No 
> operations allowed after connection closed.{*}'  My connector's code does use 
> jdbc conn, but when I use sql-client to test the connector with the same SQL, 
> it's ok. So  I wonder if there is a problem with the execution environment of 
> 'flink run -python'
