>          Components: Client
>    Affects Versions: 1.0.0, 1.3.0, 1.2.1, 0.98.19
>            Reporter: stack
>            Assignee: stack
>            Priority: Blocker
>             Fix For: 1.3.0, 1.2.2, 1.1.6

> A big batch put followed by a batch get does not always return all Cells put. See attached
test program by Robert Farr that reproduces the issue. It seems to be an issue to do with
a cluster of more than one machine. Running against a single machine does not have the problem
(though the single machine may have many regions). Robert was unable to make his program fail
with a single machine only.
> I reproduced what Robert was seeing running his program. I was also unable to make a
single machine fail. In a batch of 1000 puts, I see one to three Gets fail. I noticed too
that if I wait a second after a fail and then re-get, the Get succeeds.
