title: HDFS intracluster copy with selected columns
body: <p>I am using Avro files to store data in HDFS. I have a requirement to copy selected columns data from one avro file and send it to another location in the same cluster with its own schema file (that has the selected columns information). How can I do that? Is it possible to implement using Hive? or is there any utility in HDFS that can help me do that?</p>
  
  <p>This is required because a group must be able to access an entire table and another group should be able to access only few columns. So, I need them to be in a separate location in HDFS with only the required schema and avro file.</p>
