> Caused by: org.apache.kafka.common.errors.InvalidRequestException: MemberId
> can't be empty. {code}
> {*}Root Cause{*}:
> The following hearbeat requests might happen in flight simultaneously in new
> consumer:
> - The first heartbeat, which will get memberId from group coordinator
> (memberEpoch = 0)
> - The next heartbeat after an unsubscribe event (memberEpoch = -1)
> The second heartbeat will be sent with empty memberId while the first
> heartbeat is still in flight. And the coordinator won't accept it (memberId =
> empty, memberEpoch = -1 ).
> This corner case occurs only when unsubscribe() is called shortly after the
> first poll.
