Stephen Sisk commented on BEAM-2005:
------------------------------------
I don't want to derail this conversation, but I did have a couple other
concerns - 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".
I also believe that since Beam FileSystem objects are configured via
PipelineOptions, we need to pass a Hadoop Configuration through
PipelineOptions. I think that's very solvable, but it does seem
semi-complicated.
I'm going to open subtasks for discussion so we can discuss in separate threads.
> Add a Hadoop FileSystem implementation of Beam's FileSystem
> -----------------------------------------------------------
>
> Key: BEAM-2005
> URL: https://issues.apache.org/jira/browse/BEAM-2005
> Project: Beam
> Issue Type: New Feature
> Components: sdk-java-extensions
> Reporter: Stephen Sisk
> Assignee: Stephen Sisk
> Fix For: First stable release
>
>
> Beam's FileSystem creates an abstraction for reading from files in many
> different places.
> We should add a Hadoop FileSystem implementation
> (https://hadoop.apache.org/docs/r2.8.0/api/org/apache/hadoop/fs/FileSystem.html)
> - that would enable us to read from any file system that implements
> FileSystem (including HDFS, azure, s3, etc..)
> I'm investigating this now.
