将数据从mysql加载到Redis集群时出错

i'm new to both Redis and Go Language, so just bear with me. I'm trying to load some mysql data to the redis cluster.

I'm using this code from gitHub:Go program to load mysql data to redis

Using this, I'm able to load mysql data to a redis instance that is acting as a standalone redis server(127.0.0.1:7000).

But when i'm trying to load the same data to the nodes in a redis cluster(having 3 masters(127.0.0.1:7000,7001,7002)), i'm getting the following exception:

hmset error: MOVED 12937 127.0.0.1:7001

My redis.config for node running on port 7000:

port 7000
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 5000
appendonly yes
protected-mode no

Can somebody suggest why this is happening? Thanks in advance.
