> When visiting Ambari's dashboard, there are 3 mini charts which show quick status of
HDFS, MapReduce & HBase services. For HDFS it is the Capacity free/used, for MapReduce
it is time-series data about jobs running, and for HBase is the request counts.
> Also need to expose metrics to render Dashboard and Service Summaries.
> HDFS service's API needs to output the service's capacity (used/remaining/total) and
Block status - PendingReplicationBlocks, UnderReplicatedBlocks, as these will be needed to
show graphs in the UI.
