--------------------------------------
[~appy] Yeah, passing states across mappers is impossible. I think in the
context of the exportSnapshot, if without retry, we can verify that at
destination, there is nothing (clean). If it is retryable, it will succeed and
we can verify that everything is copied over. Going through the code, it seems
that it is not hard to add. I can add that in the test. Thanks.

> The root cause is that conf.setInt("mapreduce.map.maxattempts", 10) is not
> taken by the mapper job, so the retry is actually 0. Debugging to see why
> this is the case.
