> Typically a user submits jobs with similar characteristics. Aggregating the following metrics based on users can help
> quickly identify VIP users and how their jobs look like:
> -       slot-hours used for map tasks, for reduce tasks
> -       total jobs, jobs failed
> -       data-local-maps,  rack-local-maps, remote-maps
> -       total map-input-bytes, reduce-output-records
> -       total map tasks, total reduce tasks
> The granularity of the aggregation can be as coarse as daily. Data may be used to report top-K users in certain
> categories. Data shall be available as chukwa records (namely, one record per day per user).
