Alan Gates updated HIVE-10521:
------------------------------
Attachment: HIVE-10521.patch
Attaching a patch that changes timeOutTxns to loop through and time out all old
transactions instead of only the first 20 it finds.
[~ekoifman], can you review this?
[~sushanth], can I commit this to the 1.2 branch?
> TxnHandler.timeOutTxns only times out some of the expired transactions

> Key: HIVE-10521

> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 0.14.0, 1.0.0, 1.1.0
> Reporter: Alan Gates

> {code}
> for (int i = 0; i < 20 && rs.next(); i++) deadTxns.add(rs.getLong(1));
> // We don't care whether all of the transactions get deleted or not,
> // if some didn't it most likely means someone else deleted them in the
> interum
> if (deadTxns.size() > 0) abortTxns(dbConn, deadTxns);
> {code}
> While it makes sense to limit the number of transactions aborted in one pass
> (since this get's translated to an IN clause) we should still make sure all
> are timed out. Also, 20 seems pretty small as a batch size.
