Hi Fernando, It is recommended that you run ZooKeeper separate from the Region Servers. On the memory side, our use of ZooKeeper in terms of data stored is minimal currently. However you definitely don't want it to swap and you want to be able to handle a large number of connections. A safe value would be something like 1GB.
