cluster load history: emissions and graphs
------------------------------------------
Key: HBASE-625
URL: https://issues.apache.org/jira/browse/HBASE-625
Project: Hadoop HBase
Issue Type: Improvement
Reporter: stack
hbase should write loadings on a period in a format that is amenable to tools
like ganglia (rrd). Master can dump cluster loadings and averages.
Regionservers would report their own loadings. Should exploit the work up in
hadoop for doing this kinda thing (GangliaContext) where it makes sense. Extra
browning points if user can optionally enable display of graphs in the hbase UI
(JRobin).
