extends Object

hadoop 3.3.1 changed the return value of this method from DatanodeInfo[] to DatanodeInfoWithStorage[], which causes the JVM can not locate the method if we are compiled with hadoop 3.2 and then link with hadoop 3.3+, so here we need to use reflection to make it work for both hadoop versions, otherwise we need to publish more artifacts for different hadoop versions...
