> There is a race condition in {{TaskExecutor}} between starting registering to RM and
checking registration timeout. Currently we start RM leader retriever first, and then start
registration timeout checking. If registration is fast enough, there is a possibility that
registration is finished before starting checking registration timeout. The timeout checking
will fail later.
> There is a stack trace of exception below:
