Subject [jira] [Commented] (HDFS-6824) Additional user documentation for HDFS encryption.
Date Tue, 05 Aug 2014 23:27:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14086971#comment-14086971
] 

Andrew Wang commented on HDFS-6824:
-----------------------------------

[~tucu00] relayed a few clarifications he'd like here too:

{quote}
HDFS never stores or has access to unencrypted data or *unencrypted* data encryption keys.
A rogue user can collect keys to *files they have access to*, and use them later to decrypt
encrypted *data of that file*.
*As the user had access to the file, he already had access to the file contents*.
