Esteban Gutierrez created HBASE-17305: -----------------------------------------
Summary: 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 Assignee: 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
