ATTACHMENT ID: 12750421 - PreCommit-HIVE-TRUNK-Build
> ACID: Improve transaction Abort logic due to timeout
> ----------------------------------------------------
>
> Key: HIVE-11317
> URL: https://issues.apache.org/jira/browse/HIVE-11317
> Project: Hive
> Issue Type: Bug
> Components: Metastore, Transactions
> Affects Versions: 1.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Labels: triage
> Attachments: HIVE-11317.2.patch, HIVE-11317.3.patch, HIVE-11317.patch

>
> the logic to Abort transactions that have stopped heartbeating is in
> TxnHandler.timeOutTxns()
> This is only called when DbTxnManger.getValidTxns() is called.
> So if there is a lot of txns that need to be timed out and the there are not
> SQL clients talking to the system, there is nothing to abort dead
> transactions, and thus compaction can't clean them up so garbage accumulates
> in the system.
> Also, streaming api doesn't call DbTxnManager at all.
> Need to move this logic into Initiator (or some other metastore side thread).
> Also, make sure it is broken up into multiple small(er) transactions against
> metastore DB.
> Also more timeOutLocks() locks there as well.
> see about adding TXNS.COMMENT field which can be used for "Auto aborted due
> to timeout" for example.
> The symptom of this is that the system keeps showing more and more Open
> transactions that don't seem to ever go away (and have no locks associated
> with them)
