Group doesn't recover after internet connectivity issue about kafka

I also encountered this problem. I add a goroutine checking registration and registering again after connection broken, it seems working.

I solved my problem by sending an error into cg.errors channel like this (about consumer_group.go#L264):

cg.Logf("Currently registered consumers: %d\n", len(cg.consumers))
if len(cg.consumers) == 0 {
    cg.errors <- &sarama.ConsumerError{
        Topic:     "-",
        Partition: -1,
        Err:       fmt.Errorf("No consumer registered"),
    }
    return
}

This gives an opportunity to the caller to receive a notification by reading from Errors(). If this occurs then I close the group and restart it. It works ok.

side note: I found later that cg.errors doesn't receive any error from Sarama since config.Consumer.Return.Errors is false. By setting this to true Errors() should receive connection errors...

Uh... did you use the latest version?
