Subject [jira] [Commented] (AMBARI-8724) Rolling Upgrade - Upgrade Pack to restart standby ResourceManager first, failover, and then upgrade the remaining RM
Date Tue, 16 Dec 2014 22:43:15 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-8724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14249100#comment-14249100

Nate Cole commented on AMBARI-8724:
-----------------------------------

@jonathan - Thanks for reviewing!  Possibly {{hosts="active-master"}} and {{hostType.active/hostType.standby}}
?  Maybe isEmpty() is clearer, I personally prefer positive tests unless strong-armed.  Meh.

> Runbook outlines that RM needs to first upgrade the standby, then failover to make the
upgrade standby the active, and then upgrade the RM that is now the standby.
