Question

我正在尝试使用

创建一个kafka主题

$KAFKA_HOME/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic testing

但报告了以下错误：

Error while executing topic command : Not all brokers have rack information. Add --disable-rack-aware in command line to make replica assignment without rack information.
[2018-01-23 15:03:44,471] ERROR kafka.admin.AdminOperationException: Not all brokers have rack information. Add --disable-rack-aware in command line to make replica assignment without rack information.

zookeeper

$KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties

和kafka-server

$KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties

已成功启动。

添加--disable-rack-aware将解决此问题，但如何使用机架信息进行副本分配？

我想不是所有的经纪人都有机架配置。给密钥broker.rack grep你的server.properties。如果仅在某些但不是所有服务器配置中出现，则这是导致问题的原因。
