[jira] [Created] (HIVE-6409)
FileOutputCommitterContainer::commitJob() cancels delegation tokens too
early.
Mithun Radhakrishnan created HIVE-6409:
------------------------------------------
Summary: 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
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.

The problem is that this happens before abortJob() has had a chance to run, thus yielding the following error:
{code}

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