> There are many different reasons why an app recovery could fail with an
> exception, causing the RM start to be aborted. If that happens the RM will
> fail to start. Presumably, the reason the RM is trying to do a recovery is
> that it's the standby trying to fill in for the active. Failing to come up
> defeats the purpose of the HA configuration. Instead of preventing the RM
> from starting, a failed app recovery should log an error and skip the
> application.
