Subject [jira] [Commented] (YARN-3893) Both RM in active state when Admin#transitionToActive failure from refeshAll()
Date Tue, 14 Jul 2015 05:56:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14625866#comment-14625866
] 

Varun Saxena commented on YARN-3893:
------------------------------------

*Reinitialization of Active Services is required*. When you call stop active services, service
state for all the services will change to STOPPED.
If this RM were to become active again, we will try to start all the active services and services
cant transition to START state from STOPPED state. They can only do so when services are in
INIT state.
