Jerome Boulon commented on CHUKWA-369:
--------------------------------------

Ari, I've been busy doing something else but I want to ask some questions before someone gives
an eventual +1, in the mean time I will review your patch:
- Do you need to get your ack from the same collector you have sent the data to?
- What happen when the collector rotate?
- What happen if someone put a real HTTP load balancer in front of collector?
- Do we have a long running connection between agent and collector?

> We like to say that Chukwa is a system for reliable log collection. It isn't, quite,
since we don't handle collector crashes.  Here's a proposed reliability mechanism.
