> 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.
