I think this highly depends on the risk that you want to be exposed to. If you have it on dedicated nodes there is less influence of other processes.
I have seen both: on Hadoop nodes or dedicated. On Hadoop I would not recommend to put it on data nodes/heavily utilized nodes. Zookeeper does not need many resources (if you do not abuse it) and you may think about putting it on a dedicated small infrastructure of several nodes. > On 3 Mar 2017, at 09:15, Mich Talebzadeh <mich.talebza...@gmail.com> wrote: > > > hi, > > In DEV, Kafka and ZooKeeper services can be co- located.on the same physical > hosts > > In Prod moving forward do we need to set up Zookeeper on its own cluster not > sharing with Hadoop cluster?
