Haohui Mai reopened HADOOP-12469:
---------------------------------

Reopening the jira.

Sorry for the noise -- I realized that I haven't posted my +1 on the patch before committing.
Taking a closer look the patch, it does not seem to really address the problem. I'm going
to revert it now.

> {{RetriableFileCopyCommand.CopyReadException}} is double-wrapped via

> # via {{CopyMapper#copyFileWithRetry}}
> before {{CopyMapper::handleFailure}} tests 
> {code}
> if (ignoreFailures && exception.getCause() instanceof

> which is always false.
> Orthogonally, ignoring failures should be mutually exclusive with the atomic option otherwise
