       <![CDATA[This method is here so that when invoked, HdfsConfiguration is class-loaded if
  it hasn't already been previously loaded.  Upon loading the class, the static
  initializer block above will be executed to add the deprecated keys and to add
  the default resources.   It is safe for this method to be called multiple times
  as the static initializer block will only get invoked once.

  This replaces the previously, dangerous practice of other classes calling
  Configuration.addDefaultResource("hdfs-default.xml") directly without loading
  HdfsConfiguration class first, thereby skipping the key deprecation]]>
