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.
> Rolling Upgrade - Upgrade Pack to restart standby ResourceManager first,
> failover, and then upgrade the remaining RM
