> 1) Handle missing methods and implementation changes in core code.
>  * In [ZKWatcher.java|https://github.com/apache/hbase/blob/12786f80c14c6f2c3c111a55bbf431fb2e81e828/hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/ZKWatcher.java#L79], variable znodePaths has now been made private from public (See HBASE-19761). Currently the script directly tries to reference znodePaths which will result in exception.
>  * Also, joinZNode method is moved to ZNodePaths and removed from ZKUtil (See HBASE-19200). The script relies on non-existant ZKUtil.joinZNode().
> 2) Close zk watcher while list draining servers: The list functionality does not close the zkw instance.
