What methods are available for moving files into an HDFS Encryption Zone?

[#1]

is distcp the best/only mechanism for moving files into an encryption zone? The documentation says so. But would an hdfs mv or cp also work just fine?

[#2]

You should be use copyFromLocal or any other commands as well to copy files into EZ. You would not be able to use mv from an EZ

[#3 · Accepted solution]

The 'hadoop' command-line natively supports Encryption Zones so most file system operations (copyFromLocal, put, distCp) will work.

See more example usage in the Apache Hadoop docs.

And note that there are some considerations for copying between encrypted and unencrypted locations.

With distcp, you'll be able to encrypt a large set of data faster.

Don't forget to add the distcp command options:

--skipcrccheck --update
