[jira] [Created] (HIVE-9614) Encrypt mapjoin tables

Brock Noland created HIVE-9614:
----------------------------------

             Summary: Encrypt mapjoin tables
                 Key: HIVE-9614
                 URL: https://issues.apache.org/jira/browse/HIVE-9614
             Project: Hive
          Issue Type: Sub-task
            Reporter: Brock Noland


When performing a MapJoin we store data which is put in the distributed cache which is stored on local disk. Ideally we would encrypt these tables to the same degree that the they are encrypted in HDFS or find some other way to ensure they are encrypted.
