> Project: Hadoop Common
> Issue Type: Bug
> Components: tools/distcp
> Affects Versions: 2.7.1
> Reporter: Gera Shegalov
> Assignee: Mingliang Liu
> Priority: Critical
> Attachments: HADOOP-12469.000.patch

>
> {{RetriableFileCopyCommand.CopyReadException}} is double-wrapped via
> # via {{RetriableCommand::execute}}
> # via {{CopyMapper#copyFileWithRetry}}
> before {{CopyMapper::handleFailure}} tests
> {code}
> if (ignoreFailures && exception.getCause() instanceof
> RetriableFileCopyCommand.CopyReadException
> {code}
> which is always false.
> Orthogonally, ignoring failures should be mutually exclusive with the atomic option otherwise an incomplete dir is eligible for commit defeating the purpose.
