> Per YARN-2005, there is now a way to blacklist nodes for AM purposes so the 
> next app attempt can be assigned to a different node.
> However, currently the condition under which the node gets blacklisted is 
> limited to {{DISKS_FAILED}}. There are a whole host of other issues that may 
> cause the failure, for which we want to locate the AM elsewhere; e.g. disks 
> full, JVM crashes, memory issues, etc.
> Since the AM blacklisting is per-app, there is little practical downside in 
> blacklisting the nodes on *any failure* (although it might lead to 
> blacklisting the node more aggressively than necessary). I would propose 
> locating the next app attempt to a different node on any failure.
