I have had Kafka installed with Hadoop/Spark/etc in a comparable cluster,
except that I didn't have Kafka brokers installed in the nodes with
zookeeper. As long as physical disk space in the rest of the nodes is not a
concern, you will be OK.
I don't have enough background with Cassandra. But I can talk about HBase.
I separated Kafka brokers and HBase region servers as they are both disk
I/O intensive.
