Description

This is a demand for Hadoop-5438.
Also another small improvement is that i saw that in the beginning of readObject, it tries to get the class from PRIMITIVE_NAMES and then conf. Maybe it is better to add a direct load after them if the delaredClass is still null. Like this:

String className = UTF8.readString(in);
    Class<?> declaredClass = PRIMITIVE_NAMES.get(className);
    if (declaredClass == null) {
      try {
        declaredClass = conf.getClassByName(className);
      } catch (Exception e) {
      }
    }
    
    if(declaredClass == null) {
      try {
        declaredClass = Class.forName(className);
      } catch (ClassNotFoundException e) {
        throw new RuntimeException("readObject can't find class " + className, e);
      }
    }
