> here is my test,the Test show the client may consume the queue in some case. 
> because of the current Group rebalance is doing by the consumer side,some 
> case , the consumer may have diffent view of All Consumer ids.
> for Example: the consumer id 1 see have 3 consumers,but the consumer id 2 
> only see 2 consumers, so the same queue may hold by two consumer.
> Kakfa 0.8.2 to 0.9 have redesign the client, move the Group rebalance to 
> server side, have we need also move the Rebalance to server size ??
