   Let take Spark Thrift Server and Spark Connect as examples, `ADD JAR` is an 
end-user user operation and the artifacts can be changed by themselves. 
Starting and maintaining the Server is for system admins.  If the jar issue 
occurs here, shall we give enough time for admins to detect the issue and then 
gracefully reboot it to reduce the impact on other concurrent users.
