Subject [jira] [Updated] (YARN-3705) forcemanual transitionToStandby in RM-HA automatic-failover mode should change elector state
Date Thu, 11 Jun 2015 21:05:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-3705?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Masatake Iwasaki updated YARN-3705:
-----------------------------------
    Attachment: YARN-3705.001.patch

I attached 001 which apply quick fix of the issue. I need more consideration to add monitoring
by HealthMonitor to AdminService. If it turns out to be worth adding, I will file a follow-up
JIRA.

> Executing {{rmadmin -transitionToStandby --forcemanual}} in automatic-failover.enabled
mode makes ResouceManager standby while keeping the state of ActiveStandbyElector. It should
make elector to quit and rejoin in order to enable other candidates to promote, otherwise
forcemanual transition should not be allowed in automatic-failover mode in order to avoid
confusion.
