> ACID: Improve transaction Abort logic due to timeout

>             Project: Hive
>          Issue Type: Bug
>          Components: Metastore, Transactions
>    Affects Versions: 1.0.0
>            Reporter: Eugene Koifman
>            Assignee: Eugene Koifman
>              Labels: triage

>
> 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)
