> Many organizations are looking at resource usage per department/group/user for diagnostic
and resource allocation purposes.  It should be straightforward to implement a metric showing
the simple resource usage like CPU time and disk I/O per user and aggregate them using Ganglia.
> Eventually, we can create an API for pluggable metrics (there is one for Jobtracker and
Tasktracker).
> Let me know your thoughts.
