> The cluster id will set once we become the active master in 
> finishActiveMasterInitialization, but the blockUntilBecomingActiveMaster and 
> finishActiveMasterInitialization are both called in a thread to make the 
> constructor of HMaster return without blocking. And since HMaster itself is 
> also a HRegionServer, it will create a Connection and then start calling 
> reportForDuty. And when creating the ConnectionImplementation, we will read 
> the cluster id from zk, but the cluster id may have not been set yet since it 
> is set in another thread, we will get an exception and use the default 
> cluster id instead.
> I always get this when running UTs which will start a mini cluster
