Error while executing topic command : replication factor: 3 larger than available brokers: 2

kafka-topics.sh --zookeeper 130.51.23.249:5101 --create --topic UserLoginLog --replication-factor 3 --partitions 1
# 会报错
Error while executing topic command : replication factor: 3 larger than available brokers: 2
[2018-12-12 17:02:16,220] ERROR kafka.admin.AdminOperationException: replication factor: 3 larger than available brokers: 2

解决：replication-factor个数不能超过broker的个数。需改为少于等于2个。
