Subject [jira] Commented: (HIVE-1667) Store the group of the owner of the table in metastore
Date Mon, 27 Sep 2010 22:22:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12915516#action_12915516

Namit Jain commented on HIVE-1667:

Is it true that the first group is always the primary group (like Unix) ?
If org.apache.hadoop.security.UserGroupInformation guarantees that, your approach seems correct.

One more thing to check is what happens in case of creation of a partition via insert overwrite
The temp. folder is moved to the final folder, so you may have to fix there also.

> Currently, the group of the owner of the table is not stored in the metastore.
> Secondly, if you create a table, the table's owner group is set to the group for the
parent. It is not read from the UGI passed in.
