   Hi @codelipenghui 
   
   > We also should consider to avoid a topic can be closed more than once.
   
   I have appended the reason why `topic.close` was executed twice to the Motivation, and in this PR I've overwritten the `topic.close` to fix it. I also added a lock to the 'reset topic stat to UN-fenced' operation, could you review the code.
   
    > We can use map.compute() to simplify the logic? 
   
   Unfortunately, we can't use `map.compute` tto simplify the logic.
   
   > And looks like we don't need to wait for the future complete, because we already have the topic reference here.
    Yes, I have fixed it. The current implementation doesn't need to wait for the future to complete.
   
   I also rewritten the Motivation of this PR to make it easier to understand. Thanks.
