Chris Lambert updated AURORA-913:
---------------------------------

> Replace MaintenanceMode field with HostAttributes in HostOffer
> --------------------------------------------------------------
>
>                 Key: AURORA-913
>                 URL: https://issues.apache.org/jira/browse/AURORA-913
>             Project: Aurora
>          Issue Type: Story
>          Components: Scheduler
>            Reporter: Bill Farner
>
> Address this TODO:
> {noformat}
>   /**
>    * Encapsulate an offer from a host, and the host's maintenance mode.
>    */
>   class HostOffer {
>     private final Offer offer;
>     // TODO(wfarner): Replace this with HostAttributes for more use of this caching.
>     private final MaintenanceMode mode;
> {noformat}
> Success here will mean avoiding O(n) (n=num offers) fetching of host attributes associated
with offers when scheduling a task.
