Review comment:
> shall we log something if we fail to bind the port?
there will be a requirement here
https://github.com/apache/spark/pull/28651/files#diff-ee6e4132bcb9b33369bd5a3567937607R58
after this.
Maybe enough for checking？
I think it might be unnecessary to log for each failed round.
> or fail here?
We can not fail in this match-case. this is also for other services
registered. or maybe we can add another case for matching - `case t:
ThriftCLIService =>`?
