Sean Owen commented on SPARK-17945:
-----------------------------------

You can just set this with the S3 APIs directly? this borders or something it's 
not worth Spark passing-through just for S3 unless there's a common use case 
for it and possibly other FSes

> Writing to S3 should allow setting object metadata

> I can't find any possible way to use Spark to write to S3 and set user object 
> metadata. This seems like such a simple thing that I feel I must be missing 
> somewhere how to do it....but I have yet to find anything.
> I don't know what all work adding this would entail. My idea would be that 
> there is something like:
> rdd.saveAsTextFile(s3://testbucket/file).withMetadata(Map<String,String> 
> data).
