hbase-site.xml property placeholder

[Ben Cuthbert]

All

We are running a large setup for hbase and it would be good to be able to run 1 
property file for the whole cluster. so we can can change values
in the hbase-site.xml. Is there a way to have the hbase-site.xml read from the 
env?

something like

<property>
                <name>hbase.zookeeper.quorum</name>
                <value>${HBASE.SERVER.ZOOKEEPER.QUORUM}</value>
        </property>
