Does Hbase backup process support encryption while transporting the data from one cluster to other cluster

[neo0731]

Question arises when migrating the data from one hbase table to another.

Input

To sync the production cluster data with dev cluster. Additionaly, while
copying we need to re-hash the following fields: hashed_email, lexer_id,
foo_imsi, foo_msn, signal_uid, bar_imsi.

Question is : Does copyTable support hashing of data while copying? Same for
distcp utility ? Is it possible to supply some example code in scala as well

Any help on it would be much appreciated?
