Consuming from a replica

[Simon Cooper]

Hi,

I've been looking at the SimpleConsumer example, and that I've noticed that it 
always reads from the leader, and reacts to leader changes by reconnecting to 
the new leader. Is it possible to read from a replica in ISR that's not the 
leader? If so, how does the consumer get notified the replica it's reading from 
is no longer in ISR?

Thanks,
