Subject [jira] [Commented] (HIVE-2936) Warehouse table subdirectories should inherit the group permissions of the warehouse parent directory
Date Mon, 09 Apr 2012 20:09:17 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13250123#comment-13250123

Rohini Palaniswamy commented on HIVE-2936:
------------------------------------------

Created a clone of HIVE-2904 to address some issues with inheriting permissions. Please refer
to HIVE-2904 for prior history and discussions. 

Description of changes:
Added hive.warehouse.subdir.inherit.perms which is false by default. The default behaviour
of hive-0.8 stays. i.e directories will be created with the permissions of dfs.umask or dfs.umaskmode.
If hive.warehouse.subdir.inherit.perms is set to true, then table directories will inherit
the permission of the default warehouse or the custom database location. This comes in handy
when you have databases created with different permissions or if the warehouse directory has
permissions like 775.

There should be a option to inherit the permissions of the parent directory (default warehouse
or custom database directory) so that the table directories have the same permissions as the
database directories.
