[jira] [Created] (HBASE-21629) draining_servers.rb is broken

Nihal Jain created HBASE-21629:
----------------------------------

             Summary: draining_servers.rb is broken
                 Key: HBASE-21629
                 URL: https://issues.apache.org/jira/browse/HBASE-21629
             Project: HBase
          Issue Type: Bug
          Components: scripts
    Affects Versions: 2.1.1, 3.0.0, 2.1.2
            Reporter: Nihal Jain
            Assignee: Nihal Jain


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.
