> After enabling RM HA, one of the hosts is active (say c6401), the other is
> standby (say c6402). From that point on, YARN summary page will only show
> info if c6401 is running, whether it's active or not. The queue memory graph
> is also broken.
> If I stop RM on c6401, summary info is n/a. if I start it, even if it's
> standby, then data shows.
> Logout / login doesn't change it. Reload page doesn't change it.
> Just seems that Ambari is "holding onto" the first active RM after the wizard
> is done.
