Pradeep, attributes show up as name value pairs in the offers. Custom attributes can also be used in Fenzo for assignment optimizations. For example, we set custom attributes for AWS EC2 ZONE names and ASG names. We use the ZONE name custom attribute to balance tasks of a job across zones via the built in constraint plugin, BalancedHostAttributeConstraint <https://github.com/Netflix/Fenzo/blob/master/fenzo-core/src/main/java/com/netflix/fenzo/plugins/BalancedHostAttrConstraint.java>
