> HiveTxnManager should be stateless
> ----------------------------------
>
> Key: HIVE-7256
> URL: https://issues.apache.org/jira/browse/HIVE-7256
> Project: Hive
> Issue Type: Bug
> Components: Locking
> Affects Versions: 0.13.1
> Reporter: Eugene Koifman
> Assignee: Alan Gates
>
> In order to integrate HCat with Hive ACID, we should be able to create an
> instance of HiveTxnManager and use it to acquire locks, and release locks
> from a different instance of HiveTxnManager.
> One use case where this shows up is when a job using HCat is retried, since
> calls to TxnManager are made from the jobs OutputCommitter.
> Another, is HCatReader/Writer. For example, TestReaderWriter, calls
> setupJob() from one instance of OutputCommitterContainer and commitJob()
> from another instance. The 2nd case is perhaps better solved by ensuring
> there is only 1 instance of OutputCommitterContainer.
