| LocatedBlockHelper |
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... |
