> In our test env, QA hang one of the connecting broker of the producer, then 
> the producer will be stuck in send method, and throw the exception: fail to 
> update metadata after request timeout.
> I found the reason as follow:  when the producer chose one of the broker to 
> send metadata, it connect to the broker, but the broker is hang, the tcp is 
> connected and Network client marks this broker is connected, but the SSL 
> channel is not ready yet so the channel is not ready.    
> Then the Network client chooses the connected node in the leastLoadedNode 
> every time to send the metadata, but the node's channel is not ready yet.  
> So the producer stuck in getting metadata and will not try another node to 
> request metadata.  The client should not stuck only one node is hung
