> If a client gets a connection from ZkClientPool and then closes the connection by calling zkClient.close(), any future calls to getZkClient will NPE. The pool attempts to check if the connection is valid by calling "zkClient.getConnection().getZookeeperState() == States.CONNECTED", but for a closed connection the getConnection() call returns null.
> Further, there is currently no way to ask the pool itself to close connections. There is a reset method, but reset simply discards the reference to the connection without closing it. ZkConnectionPool.reset() should close connections before dereferencing them.
