Isolating ZooKeeper Nodes
Provides an overview on how to install a ZooKeeper-only node.
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 data-fabric from
using this node for data storage.
