Sravya Tirukkovalur commented on SENTRY-1345:
---------------------------------------------
[~hahao] Good point, added more details on the problem to the jira. Regarding
opening a new connection in the test, I do not think it is necessary as all
hive commands in the test are being run as the same user.
> ACLS on table folder disappear after insert for unpartitioned tables

> Key: SENTRY-1345
> URL: https://issues.apache.org/jira/browse/SENTRY-1345
> Project: Sentry
> Issue Type: Bug
> Affects Versions: 1.7.0
> Reporter: Sravya Tirukkovalur
> Assignee: Sravya Tirukkovalur
> Fix For: 1.8.0

> Attachments: SENTRY-1345.patch

> This seems to be due to the fact that onAlterTableEvent is being trigged for
> this operation of "INSERT on a unpartitioned table" in Hive. And sentry- hive
> plugin thinks this is an alter table location command, and we add the new
> path and delete the old path for this Hive object. As add happens first and
> then the delete on the same path in this case, the path is lost resulting in
> no acls on this path.
> Workaround: This gets corrected at the next HMS restart.
> We can fix on Sentry side to not do add/delete if oldPath == newPath. But we
> also need to understand the Hive behavior.
> Not exactly sure when this regressed as we dont seem to have coverage for it.
> Also adding a test case as part of the patch which can be used against older
> versions.
