Gera Shegalov commented on HADOOP-12473:
----------------------------------------
Hi [~mithun] I understand atomic as "all or nothing". '-i' would allow a subset
to be committed should there be failures with the job succeeding.
> distcp's ignoring failures option should be mutually exclusive with the
> atomic option

>
> In {{CopyMapper::handleFailure}}, the mapper handles failure and will ignore
> it if no it's config key is on. Ignoring failures option {{-i}} should be
> mutually exclusive with the {{-atomic}} option otherwise an incomplete dir is
> eligible for commit defeating the purpose.
