[jira] Updated: (PIG-987) Zebra Column Group Access Control
[ https://issues.apache.org/jira/browse/PIG-987?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yan Zhou updated PIG-987:
-------------------------
Summary: Zebra Column Group Access Control (was: Zebra Column Group Access Control for A29 compliance and Performance)
> Zebra Column Group Access Control
> ---------------------------------
>
> Key: PIG-987
> URL: https://issues.apache.org/jira/browse/PIG-987
> Project: Pig
> Issue Type: New Feature
> Affects Versions: 0.6.0
> Reporter: Yan Zhou
> Assignee: Yan Zhou
> Attachments: A29_ColumnGroupSecurity.patch
>
>
> Access Control: when processes try to read from the column groups, Zebra should be able to handle allowed vs. disallowed user/application accesses.
> Expected behavior when column group permissions are set:
> When user selects only columns that they do not have permissions to access, Zebra should return error with message "Error #: Permission denied for accessing column <column name or names>
> Access control applies to an entire column group, so all columns in a column group have same permissions.
