CR Hota commented on HDFS-14577:
--------------------------------
[~elgoiri] Thanks for the review.
ReflectionUtils is quite diverged from FederationUtil. One might need conf to
create the object itself. Yes setConf is present but that is after the object
creation. Also this is something that can be done by the developer itself,
after the instance reference is given back.
The use cases are to create FairnessManager and also SecurityManager which need
just the conf object and standardize pluggable object creation.
May be at some point we may look to deprecate FederationUtil and enhance
ReflectionUtil to help create all objects (nnresolver, statestore resolver,
fairness, security).

> FederationUtil#newInstance either works for empty constructor or constructor
> with conf and context class. More use cases are coming along where conf is
> the only param needed to construct objects.
