> Key: HBASE-16010
> URL: https://issues.apache.org/jira/browse/HBASE-16010
> Project: HBase
> Issue Type: Improvement
> Reporter: Jerry He
> Assignee: Matt Warhaftig
> Priority: Minor
> Fix For: 2.0.0

> Currently, there is no Amdin API for draining function. Client has to
> interact directly with Zookeeper draining node to add and remove draining
> servers.
> For example, in draining_servers.rb:
> {code}
> zkw = org.apache.hadoop.hbase.zookeeper.ZooKeeperWatcher.new(config,
> "draining_servers", nil)
> parentZnode = zkw.drainingZNode
> begin
> for server in servers
> node = ZKUtil.joinZNode(parentZnode, server)
> ZKUtil.createAndFailSilent(zkw, node)
> end
> ensure
> zkw.close()
> end
> {code}
> This is not good in cases like secure clusters with protected Zookeeper nodes.
> Let's put draining function through Admin API.
