Subject [jira] [Commented] (HDFS-10899) Add functionality to re-encrypt EDEKs.
Date Wed, 08 Feb 2017 01:46:41 GMT

Andrew Wang commented on HDFS-10899:
------------------------------------

Taking a look this week. One small note, I'm unable to apply the patch with "git apply" due
to the below error message. I think using some combination of "git diff --full-index --binary"
will make this work.

{noformat}
error: cannot apply binary patch to 'hadoop-hdfs-project/hadoop-hdfs/src/test/resources/editsStored'
without full index line
error: hadoop-hdfs-project/hadoop-hdfs/src/test/resources/editsStored: patch does not apply

> Currently when an encryption zone (EZ) key is rotated, it only takes effect on new EDEKs.
We should provide a way to re-encrypt EDEKs after the EZ key rotation, for improved security.
