> Key: HADOOP-16546
> URL: https://issues.apache.org/jira/browse/HADOOP-16546
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.2.0
> Reporter: Steve Loughran
> Priority: Major
>
> This is not a problem I've seen in the wild, but I've now encountered a problem with hive doing something like this
> we need to (somehow) make sure that the staging committers collect DTs for the staging dir FS. If this is the default FS or the same as a source or dest FS, this is handled elsewhere, but otherwise we need to add the staging fs.
> I don;t see an easy way to do this, but we could add a new method to PathOutputCommitter to collect DTs; FileOutputFormat can invoke this alongside its ongoing collection of tokens for the output FS. Base impl would be a no-op, obviously.
