[jira] [Commented] (HBASE-5209) HConnection/HMasterInterface should allow for way to get hostname of currently active master in multi-master HBase setup

Jonathan Hsieh commented on HBASE-5209:
---------------------------------------

As a suggestion, instead of adding new methods to the HMasterInterface or HConnection, how about adding and serializing data into the o.a.h.hbase.ClusterStatus object? 

If we want to get lists of the standby masters, we'd probably want to add some info into ZK in a znode such as {{/hbase/backup-masters/<masterid>}}.

> I have a multi-master HBase set up, and I'm trying to programmatically determine which of the masters is currently active. But the API does not allow me to do this. There is a getMaster() method in the HConnection class, but it returns an HMasterInterface, whose methods do not allow me to find out which master won the last race. The API should have a getActiveMasterHostname() or something to that effect.
