Isolating ZooKeeper Nodes

For large clusters (100 nodes or more), isolate the ZooKeeper on nodes that do not perform any other function. Isolating the ZooKeeper node enables the node to perform its functions without competing for resources with other processes. Installing a ZooKeeper-only node is similar to any typical node installation, but with a specific subset of packages.

Warning: Do not install the FileServer package on an isolated ZooKeeper node in order to prevent MapR from using this node for data storage.
