ZooKeeper REST implementation using Jersey JAX-RS. -------------------------------------------------- This is an implementation of version 2 of the ZooKeeper REST spec. Note: This interface is currently experimental, may change at any time, etc... In general you should be using the Java/C client bindings to access the ZooKeeper server. This REST ZooKeeper gateway is useful because most of the languages have built-in support for working with HTTP based protocols. See SPEC.txt for details on the REST binding.

There is a newer version: 3.9.3
