Ashish K Singh commented on KAFKA-3879:
---------------------------------------

[~hachikuji] yeah KAFKA-3822 is pointing to the same issue. I am trying to 
think of a case where someone would want to wait on broker to come up in close, 
but no such case to my mind. One can always set {{max.block.ms}} to 
{{Long.MAX_VALUE}} to achieve that. I am more inclined towards having something 
like {{max.block.ms}}. It will probably require a KIP, are you working on 
KAFKA-3822? If not, I can post a short (hopefully :)) KIP and a patch this week.

> KafkaConsumer with auto commit enabled gets stuck when killed after broker is 
> dead.
> * KafkaConsumer on close tries to close coordinator.
> * Coordinator, if auto commit is enabled, tries to commit offsets 
> synchronously before closing.
> * While trying to synchronously commit offsets, coordinator checks if 
> coordinator is alive by sending {{GroupCoordinatorRequest}}. As brokers are 
> dead, this returns {{NoAvailableBrokersException}}, which is a retriable 
> exception.
> * Coordinator ready check enters into an infinite loop as it keeps retrying 
> to discover group coordinator.
