Hi
I want to implement security at file level in Hadoop, essentially restricting certain data to certain users. Ex - File A can be accessed only by a user X File B can be accessed by only user X and user Y Is this possible in Hadoop, how do we do it? At what level are these permissions applied (before copying to HDFS or after putting in HDFS)? When the file gets replicated does it retain these permissions?
