Subject Re: Phoenix with multiple HBase masters
Date Wed, 07 Aug 2019 16:01:37 GMT
Great answer, Aleksandr!

Also worth mentioning there is only ever one active HBase Master at a 
time. If you have multiple started, one will be active as the master and 
the rest will be waiting as a standby in case the current active master 
dies for some reason (expectedly or unexpectedly).
