Hi why is it generally said that zk should have a separate disk of it's own? Currently in my small 5 node cluster, one of the regionservers itself is also the zk. How beneficial is it to move it to a separate machine? And in that case, what should be the machine config like?should it be ram intensive or CPU intensive or io intensive? It would be great if you could also explain the reason briefly.
Thanks, Hari
