> 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.
