You don't need to recompile the entire HBase source code. Just your code,
then deploy it to the Master server and do the config in hbase-site.xml:
<property>
<name>hbase.master.loadbalancer.class</name>
<value>org.spaggiari.hbase.RegionServerPerformanceBalancer</value>
</property>
Feel free to ask more questions if required.
