> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Hongyuan Li
> Assignee: Hongyuan Li
>
> Distcp should add a default AtomicWorkPath properties when using atomic
> {{Distcp}}#{{configureOutputFormat}} using code below to generate atomic work
> path
> {code}
> if (context.shouldAtomicCommit()) {
> Path workDir = context.getAtomicWorkPath();
> if (workDir == null) {
> workDir = targetPath.getParent();
> }
> workDir = new Path(workDir, WIP_PREFIX + targetPath.getName()
> + rand.nextInt());
> [code}
> When atomic is set and {{AtomicWorkPath}} == null, distcp will get the parent
> of current {{WorkDir}}. In this case, if {{workdir}} is {{"/"}}, the parent
> will be {{null}}, wich means
> {{workDir = new Path(workDir, WIP_PREFIX + targetPath.getName() +
> rand.nextInt());}} will throw a nullpoint exception.
