Mithun Radhakrishnan updated HIVE-6409:
---------------------------------------
Status: Patch Available (was: Open)
> FileOutputCommitterContainer::commitJob() cancels delegation tokens too early.
> ------------------------------------------------------------------------------
>
> Key: HIVE-6409
> URL: https://issues.apache.org/jira/browse/HIVE-6409
> Project: Hive
> Issue Type: Bug
> Components: HCatalog
> Affects Versions: 0.12.0, 0.13.0
> Reporter: Mithun Radhakrishnan
> Assignee: Mithun Radhakrishnan
> Attachments: HIVE-6409.trunk.patch
>
>
> When HCatalog's FileOutputCommitterContainer::commitJob() is run, it calls
> the underlying OutputCommitter and then attempts to register partitions in
> HCatalog.
> If the commit fails (for example, because of HIVE-4996), commitJob() cancels
> delegation tokens retrieved from HCatalog before the exception is rethrown.

> I'll have a patch out that only cancels delegation tokens if the commitJob()
