> 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).
