[jira] [Commented] (SPARK-17945) Writing to S3 should allow setting object metadata

["Jeff Schobelock (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-17945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15715396#comment-15715396 ] 

Jeff Schobelock commented on SPARK-17945:
-----------------------------------------

Just wanted to add some more justification to this (not sure anyone will look). The reason why I wanted this is because when I write out from Spark, to set the Object metadata after that via Java SDK APIs requires a copy of the object. I was hoping for a way to do this in one step that doesn't use the AWS CLI via shell commands form within spark, or other "hacky" things like that.

> 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).
