> 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();
> }
> }
> {code}
