Justine Olshan commented on KAFKA-16217:
----------------------------------------

Thanks [~calvinliu] for filing this bug. 
With [https://github.com/apache/kafka/pull/13591] if we are in committing state 
and try to abort when closing, we will hit an IllegalStateException and enter 
fatal state. At this point, it is not possible to complete the transaction. 
Given that the fatal state means the producer must be closed, we should allow 
closing the producer in fatal state.

The server will either abort the transaction due to timeout, or the new 
producer coming up with the same producer ID will abort the transaction.

> With the additional log, I found the root cause. If the producer is in a bad 
> transaction state(in my case, the TransactionManager.pendingTransition was 
> set to commitTransaction and did not get cleaned), then the producer calls 
> close and tries to abort the existing transaction, the producer will get 
> stuck in the transaction abortion. It is related to the fix 
> [https://github.com/apache/kafka/pull/13591].
