Error when trying to an additional cassandra node to my AIO setup

[korakode]

Hi, I am trying to add two cassandra nodes to my aio setup,So all together I have three nodes. One in my AIO setup and one each in my two nodes. My config file in my AIO setup looks like this:

IP1=xx.xx.xx.xx

IP2=yy.yy.yy.yy

IP3=zz.zz.zz

ZK_HOSTS="$IP1 $IP2 $IP3"

ZK_CLIENT_HOSTS="$IP1 $IP2 $IP3"

CASS_HOSTS="$IP1:1,1 $IP2:1,1, $IP3:1,1"

When I run this on ds profile, I am getting an error like,

[ChangeDelta, position: 274, lines: [ - seeds: "Error: wrong syntax for xx.xx.xx.xx:1,1,"] to [ - seeds: "Error: wrong syntax for yy.yy.yy.yy:1,1,"]].

I dont know what is wrong with the syntax.

Can you please help me out.

Thanks.
