> [2016-04-19 20:30:19,168] INFO [Kafka Server 1], Remaining partitions to move: __consumer_offsets-48,__consumer_offsets-13,__consumer_offsets-46,__consumer_offsets-11,__consumer_offsets-44,__consumer_offsets-42,__consumer_offsets-21,__consumer_offsets-19,__consumer_offsets-32,__consumer_offsets-30,__consumer_offsets-28,__consumer_offsets-26,__consumer_offsets-7,__consumer_offsets-40,__consumer_offsets-38,__consumer_offsets-36,__consumer_offsets-1,__consumer_offsets-34,__consumer_offsets-16,__consumer_offsets-45,__consumer_offsets-14,__consumer_offsets-12,__consumer_offsets-41,__consumer_offsets-10,__consumer_offsets-24,__consumer_offsets-22,__consumer_offsets-20,__consumer_offsets-49,__consumer_offsets-18,__consumer_offsets-31,__consumer_offsets-0,test2-0,__consumer_offsets-27,__consumer_offsets-39,__consumer_offsets-8,__consumer_offsets-37,__consumer_offsets-6,__consumer_offsets-4,__consumer_offsets-2 (kafka.server.KafkaServer)
> [2016-04-19 20:30:19,169] INFO [Kafka Server 1], Error code from controller: 0 (kafka.server.KafkaServer)
> [2016-04-19 20:30:24,169] WARN [Kafka Server 1], Retrying controlled shutdown after the previous attempt failed... (kafka.server.KafkaServer)
> [2016-04-19 20:30:24,171] WARN [Kafka Server 1], Proceeding to do an unclean shutdown as all the controlled shutdown attempts failed (kafka.server.KafkaServer)
> it is determined by :
> controlled.shutdown.retry.backoff.ms = 5000
> controlled.shutdown.max.retries=3
> It slow because the last one can not elect the new leader for the remaining partitions , the last one can improve to shutdown quickly, we can skip the shutdown error when it is the last broker
