Description

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).
