> Support atomic rename within FileSystem to replace inefficient Hadoop copy
> --------------------------------------------------------------------------
>
> Key: BEAM-2138
> URL: https://issues.apache.org/jira/browse/BEAM-2138
> Project: Beam
> Issue Type: Improvement
> Components: io-java-hadoop-file-system
> Reporter: Luke Cwik
> Priority: P3
>
> Hadoop copy operation is inefficient since it needs to stream the entirety of
> the resource through the machine performing the copy. Hadoop file system
> implementations do support an efficient rename.
> Apache Beam sinks rely on being able to rename files atomically which is
> currently done by using FileSystem copy + delete.
