-zookeeper node count

My understanding is that hbase master node and hadoop name node are the single point of failures in the cluster.
So for Production environment I will have 2 servers configured as Active / Passive Cluster with share storage, if the Active server crashed, then Passive will take over and bring up the name node / master node.
Now my only concern is the zookeeper node, right now I intend to run single zookeeper node in Active server, and configured it to be able to failover to Passive when disaster happens.
My question is can I always use 1 zookeeper node to handle all clients request? Or should I scale it according to how many client that will make read/write?
