> 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.
