We typically install Kafka on its own cluster, although it can use the
existing ZK (if its not too busy).
Otherwise Kafka can suffer from disk contention with the slaves and
CPU/memory contention with the masters.
If this is just test cluster, installing Kafka on the slaves is probably fine.

I have a 5 node cluster with one Jab tracker and another namenode; zookeeper on
job tracker, namenode and a slave (of the three).
Can you advise me on what nodes should I use for installing kafka? I am looking
for at least 2 replications.
