kafka中关于 Cannot execute because there is an existing partition assignment 报错信息的解决方案

【问题描述】

在  kafka  中执行  负载均衡操作  阶段   执行副本存储计划   时候，

 [root@hadoop11 kafka]# bin/kafka-reassign-partitions.sh --bootstrap-server hadoop11:9092 --reassignment-json-file increase-replication-factor.json --execute

出现以下提示信息：

 翻译一下大致就是：

【解决方案】

在命令后边追加上    --additional
