Junping Du commented on YARN-921:
---------------------------------
Hi Bikas, Thanks for your good suggestions here. I would follow up a email
thread to dev and get more people's feedback. Before that, I want to make sure
I understand the requirement for clone in proto objects.
First, I didn't find a perfect example to clone a proto in the same class type.
What I found are get info from one proto and set to another proto. Am I missing
something? Shouldn't semantics of clone be something like this?
{code}
x.clone() != x
x.clone().getClass() == x.getClass()
x.clone().equals(x) == true
{code}
> Consider adding clone methods to protocol objects
