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. -B On Mon, Feb 29, 2016 at 9:45 PM, Sa Li <sal...@gmail.com> wrote: > Hi, All > > I have a 9-node cluster where I already installed cloudera Hadoop/spark, > now I want to install kafka in this cluster too, is it a good idea I > install kafka on each of 9 node?
