title: Securely transferring data from HDFS to amazon S3 using distcp
body: <p>We want to backup the HDFS data in our Cloudera Hadoop cluster to Amazon S3. Looks like we can use distcp for this but what is not clear is if the data is copied to S3 over an encrypted transport. </p>
  
  <p>Is there something that needs to be configured to enable this?</p>
