Bit of polish on HBASE-1018
---------------------------
Key: HBASE-1030
URL: https://issues.apache.org/jira/browse/HBASE-1030
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
Fix For: 0.19.0
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.
