Date Thu, 28 Dec 2017 08:38:00 GMT

anishek commented on HIVE-18341:
--------------------------------

I have also tried with _ skipcrccheck_ option in distcp.options but that fails as well with
files having incomprehensible data on target warehouse.

> "a new virtual path prefix, /.reserved/raw/, that gives superusers direct access to the
underlying block data in the filesystem. This allows superusers to distcp data without needing
having access to encryption keys, and also avoids the overhead of decrypting and re-encrypting
data."
> We need to introduce a new option in "Repl Load" command that will change the files being
copied in distcp to have this "/.reserved/raw/" namespace before the file paths.
