    [ https://issues.apache.org/jira/browse/ORC-14?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17392708#comment-17392708 ] 

L-Job commented on ORC-14:
--------------------------

I read the [https://orc.apache.org/specification/ORCv1/] 、and discovery the process of unauth user will get the mask data after this feature.

so i wanna ask why don't throw an exception like permission denied ! i think this will make the problem easier.

> It would be useful to support column level encryption in ORC files. Since each column and its associated index is stored separately, encrypting a column separately isn't difficult. In terms of key distribution, it would make sense to use an external server like the one in HADOOP-9331.
