Sangjin Lee commented on YARN-3047:
-----------------------------------

One more thing: I notice that TimelineReaderManager uses object types (Long) 
for primitive types in its methods. Is there a strong reason to do this? If 
not, I would prefer staying with primitive types to avoid unnecessary boxing 
and unboxing.

I'm also going to go over the document.
