> As per the current implementation for AM blacklisting, disabling is based on complete cluster resource.
> Incase of partitioned cluster though, nodes applicable for AM labels only should be considered as total nodes.
> Additionally for unmanaged AM as AM blacklisting is not done, it is equivalent to blacklisting being disabled for this app. Hence we do not need to create a SimpleBlacklistManager object. 
> We can create DisableBlacklistManager object instead.
> {code}
>     BlacklistManager currentAMBlacklist;
>     if (currentAttempt != null) {
>       currentAMBlacklist = currentAttempt.getAMBlacklist();
>     } else {
>       if (amBlacklistingEnabled) {
>         currentAMBlacklist = new SimpleBlacklistManager(
>             scheduler.getNumClusterNodes(), blacklistDisableThreshold);
>       } else {
>         currentAMBlacklist = new DisabledBlacklistManager();
>       }
