> Two active HBase Masters can run at the same time under certain circumstances

> Key: HBASE-17305
> URL: https://issues.apache.org/jira/browse/HBASE-17305
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 2.0.0
> Reporter: Esteban Gutierrez
> Priority: Critical
>
> This needs a little more investigation, but we found a very edgy case when
> the active master is restarted and a stand-by master tries to become active,
> however the original active master was able to become the active master again
> and just before the standby master passed the point of the transition to
> become active we ended up with two active masters running at the same time.
> Assuming the clock on both masters were accurate to milliseconds, this race
> happened in less than 85ms.
