   I can reproduce this problem using multi threads to create producers and consumers for one topic at the same time.
   
   There is a race condition when we use multi clients to create producers or consumers for one topic, the broker will receive the producer command and subscribe command at the same time and try to add schemas, we need to make sure that the topic schema only updates by one thread at the same time.
