Sharad Agarwal commented on MAPREDUCE-3315:
-------------------------------------------
I meant the later one. The only difference is that I think it is better to not
expose HeartbeatRequest and HeartbeatResponse to users beacause certain fields
like actions etc are framework level. Instead these classes should composes the
fields required by the user.
