---------------------------------------

bq. Pushed to branch-1.0+ (FYI Enis Soztutar and Nick Dimiduk). 
Thanks for the ping. +1 for the patch. It is important for rolling upgrades.

> If hbase.regionserver.global.memstore.upperLimit or lowerLimit are present we should
use them instead of hbase.regionserver.global.memstore.size or hbase.regionserver.global.memstore.size.lower.limit
respectively. The current implementation of HeapMemorySizeUtil.getGlobalMemStorePercent()
and getGlobalMemStoreLowerMark() asumes that if the new properties are not defined then we
should use the old configurations, however the new properties are defined in hbase-default.xml
which makes the old configuration names useless and this has a direct impact when doing a
rolling upgrade and hbase-site.xml hasn't been changed to handle the new property names exclusively.
