  ON MVN COMPILE NOT WORKING

  If you wondering why 'mvn compile' does not work building HBase
  (in particular, if you are doing it for the first time), instead do
  'mvn package'.  If you are interested in the full story, see
  https://issues.apache.org/jira/browse/HBASE-6795.

             https://stackoverflow.com/questions/33825743/rename-files-inside-a-jar-using-some-maven-plugin

            The netty jar has a .so in it. Shading requires rename of the .so and then passing a system
            property so netty finds the renamed .so and associates it w/ the relocated netty files.

            Add this define when running unit tests:
            
               mvn test -Dorg.apache.hbase.thirdparty.io.netty.packagePrefix=org.apache.hbase.thirdparty. -Dtest=TestNettyIPC

            See toward the end of this issue for how to pass config:
            
              https://github.com/netty/netty/issues/6665

            TODO: Ensure native works.
            NOTE: The 'tofile' in the move command below has the relocation hard-coded
            with '-' instead of '.' separators. If change the relocation, need to change here too.
