Andrew Purtell commented on HBASE-1030:

If I left INFO level logging in, that's my bad. Intended to convert to DEBUG.

> HBASE-1018 added new attributes to serverload and then in the master UI, outputted the
new detailed serverload.  Looking at this w/ jgray, if hundreds of regions per server, the
UI will blow out trying to list per region load.  Jgray suggested that region-level detail
instead should show over on the regionserver itself.  Will change the UI to do as he suggests
and just leave the new summary memory used, etc., showing in the load box over in master UI.
> Doing math, we at first were afraid that the new fatter HServerLoad instance would overload
the master when hundreds of regions but doing the math and counting the attributes that make
up the new HSL, it looks like about ~128 characters per server every 3 second heartbeat, not
too much.. so that should be fine.
