Alan Gates created HIVE-10521:
---------------------------------
Summary: TxnHandler.timeOutTxns only times out some of the expired
transactions
Key: HIVE-10521
URL: https://issues.apache.org/jira/browse/HIVE-10521
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 1.0.0, 0.14.0, 1.1.0
Reporter: Alan Gates
Assignee: 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.
