Luke Cwik resolved BEAM-2030.
-----------------------------
Resolution: Fixed
> Implement beam FileSystem's copy()
> ----------------------------------
>
> Key: BEAM-2030
> URL: https://issues.apache.org/jira/browse/BEAM-2030
> Project: Beam
> Issue Type: Sub-task
> Components: sdk-java-extensions
> Reporter: Stephen Sisk
> Assignee: Luke Cwik
> Fix For: First stable release
>
>
> Beam's FileSystem has a copy() command, however I can't find a good analog in
> Hadoop's FileSystem.
> https://hadoop.apache.org/docs/r2.8.0/api/org/apache/hadoop/fs/FileSystem.html
> shows lots of copy to/from local files, but no "copy between these two
> arbitrary paths".
> cc [~davor] [~dhalp...@google.com] did either of you have thoughts about
> this? I don't think that it makes sense to have beam stream data from one
> node just so it can write it back to another node. (it could be an extension
> method, but I'd want to make it obvious that it's the inefficient version of
> things)
> My default answer here is to throw an unimplemented exception on copy or to
> remove it from the BFS interface altogether.
