> -----------------------------------
>
> Key: HBASE-20109
> URL: https://issues.apache.org/jira/browse/HBASE-20109
> Project: HBase
> Issue Type: Improvement
> Components: Client
> Affects Versions: 1.4.2
> Reporter: Andrew Purtell
> Assignee: Andrew Purtell
> Priority: Minor
> Fix For: 1.5.0
>
> Attachments: HBASE-20109-branch-1.patch
>
>
> Right now the only public API available in branch-1 to the client to learn
> the server name of the active master is Admin#getClusterStatus#getMaster,
> returning ServerName. On a cluster of any size getClusterStatus is expensive,
> especially if used only to retrieve the active master name.
> Later versions have
> {code}
> ServerName Admin#getMaster()
> {code}
> for lightweight discovery of the active master location. Add this to branch-1.
