> Chukwa HBase table schema is designed for HICC, it cannot be fully adapted to
> Ganglia web frontend for several reasons:
> (1) cannot fastly retrieve all the cluster and related host names.
> (2) system metrics have no attributes, like type, unit, so it is hard to
> explain the collected metrics by code.
> (3) lack of data cosolidate function, choosing metric for a large time range
> (like 30 days) will fetch all the data and draw graph, which will largely
> lose performance.
> We will redesign the table schema that will be better adapted to Ganglia web
> frontend queries.
