title: Reading HDFS extended attributes in HiveQL
body: <p>I am working on a use case where we would like to add metadata (e.g. load time, data source...) to raw files as HDFS extended attributes (xattrs).
  I was wondering if there was a way for HiveQL to retrieve such metadata in queries in the result set.
  This would avoid storing such metadata in each record within raw files.
  Would a custom Hive SerDe be a way to make such xattrs available? Otherwise, do you see another way to make this possible?</p>
  
  <p>I am still relatively novice with this, so bear with me if I misused terms.</p>
  
  <p>Thanks</p>
