Subject [jira] [Commented] (HDFS-10899) Add functionality to re-encrypt EDEKs.
Date Fri, 06 Jan 2017 07:34:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10899?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15803859#comment-15803859
] 

Xiao Chen commented on HDFS-10899:
----------------------------------

During the offline discussion, [~dilaver] also asked about the progress restoring logic -
the {{startAfter}} usage. It turns out in my conversion from {{getListing}} to inode based
traversal, this wasn't treated correctly.

Fixed it in patch 4, and added a unit test {{TestEncryptionZones#testRestartDuringReencrypt}}
for that. Hopefully review can be a tad easier by diff-ing patch 3 v.s. patch 4.

> 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.
