Hari Shreedharan commented on FLUME-1622:
-----------------------------------------
Denny,
As of now there is no rule or verification that happens if the event has a body
or not. So we cannot assume that it has. Also, it is possible that there are
users who would simply want to transfer event data in headers - say, just the
timestamps at which some "event" happened - in which case they may not need a
body at all. Anyway we cannot assume that the body exists.
Also note that we cannot make a new requirement that each event has a body,
unless we make the requirement in the next major release, v2.0. We have to make
sure existing client code works fine between point/minor releases. So for now,
we *need* to support the case where there is a zero-size/non-existent body.
