Alessandro Presta commented on GIRAPH-319:
------------------------------------------
Oh ok, this sounds reasonable. Feel free to make the change (I'm on vacation
without my work laptop).
In my experience, a long-running job would systematically trigger many resent
requests, which in turn caused the same number of responses to be sent back
(leading to discovering this bug).
I have yet to come across the case where a request is received multiple times
but only one response comes back, hence in practice I always got both the
"Already completed request" info and this... so the two seem kind of redundant,
but I have no strong opinion.

> Related to GIRAPH-306, and resending requests for which we haven't received
> response yet. If because of that we send request two times, and get two
> responses to it, the second one will cause an exception
