Using "controlled shut down" means Kafka will try first to migrate the partition leaderships from the broker being shut down before really shut it down so that the partitions will not be unavailable. Disabling it would mean that during the time when the broker is done until the controller noticed it and make other brokers leader of the partitions this broker originally holds as leader, these partitions will be unavailable, hence there will be an unavailability window.
More details, you can search "controlled.shutdown.enable" in https://kafka.apache.org/documentation.html#brokerconfigs On Mon, Dec 2, 2013 at 4:23 PM, Nitzan Harel <nitzan.ha...@jivesoftware.com>wrote: > The default value for "controlled.shutdown.enable" is false. > Does that mean that stopping a broker without a controlled shutdown and > using a "kill ?9" might lead to an under "UnderReplicatedPartitions" state? > -- -- Guozhang
